Addendum 1 to the 2004 Regulations for Targa Modern, Classic, Historic, and Panamericana. Issued February 25 2004 Addendum 1.1 Tires and Rims. Change Article 3.4 (b) (ii) Tires and Rims (1) Markings [Page 28] to read(1) Markings. All tires, other than those used on vehicles in the Historic Division, must carry a recognized "standards mark" eg: D.O.T, JATMA - Japan, ETRTO - European, NZS – New Zealand, ADR – Australia. The complete manufacturer’s name, tire model, size, speed rating, or load carrying capacity must be moulded on the sidewall. None of the tire’s original mouldings marks or writing may be removed. Tires must not carry the words "Not For Highway Use" The organizers reserve the right to exclude tires outside the spirit of these regulations Addendum 1.2 Replacement seats in Standard and Modified SpecificationIn Article 3.4 (d) (viii) Interior (cockpit and trunk) [page 33] replace “Replacement seats and mounting must meet current FIA regulations. Seats and mounting meeting typical category-era regulations will also be accepted but are not recommended.” and in Article 3.4 (e) (viii) Interior [page 36] replace “Seats and mounting must meet current FIA regulations. Seats and mounting meeting typical category-era regulations will also be accepted but are not recommended.” with It is recommended that replacement seats and mountings meet current FIA regulations. Alternate Seats and mountings may be used. Replacement seats and mounting must be installed so that they are securely attached to the floor of the vehicle in such a manner as to prevent the movement of the seat in case of an accident. It is strongly recommended that a barrier or crossbar in the cage structure be installed behind the seat that limits the rearward movement of the seat back in the case of a rear impact. NOTE: This regulation will be reviewed for 2005 due to expected FIA regulation changes. Addendum 1.3 Electronic Engine Management in Modified Specification

Addendum 1 - 2 - In Article 3.4 (e) (i) Engine and Ancillaries [page 34] replace “Ignition is free. Electronic engine management is free in Modern Division and in OE-equipped Classic Division cars. Electronic engine management is otherwise not allowed in Classic Division.” with Ignition is free. Electronic engine management is free in Modern Modified and Classic Modified; Electronic engine management in OE-equipped Classic and Modern Division Standard Specification cars may not be altered or enhanced. Electronic engine management is otherwise not allowed in Classic Standard Specification where it was not supplied as original equipment. NOTE: this will be reviewed for the 2005 event Addendum 1.4 “Dog Boxes” in Modified Specification In Article 3.4 (e) (ii) Gearbox/transaxle/differential/axles [page 34] replace “The means of gear selection is free (e.g. sequential-shifting gearboxes and gearboxes which do not employ clutch disengagement for gear changes (‘dog boxes’) are permitted). with The means of gear selection is free (e.g. sequential-shifting gear boxes and gearboxes which do not employ a clutch disengagement for gear changes --dog boxes-- are permitted.) The foregoing applies to Modern Modified Class only. Sequential and dog boxes are not allowed in Classic Modified. Addendum 1.5 Suspension in Standard Specification In Article 3.4 (d) (iv) Suspension [page 32] delete the paragraph that reads “Anti-roll bars, upper and lower strut bars, and anti-roll bar mounts may be modified. Camber compensators can be added, and lever-shocks replaced with a different design, but an exemption must be requested in both cases.” which contradicts the paragraph that precedes it. Anti-roll bars, strut bars and anti-roll bar mounts may not be modified. Addendum 1.6 Vehicles ineligible for Standard Specification Inset the following after the list of ineligible vehicles.Article 3.4 (d) Permitted Modifications: Standard Specification [page 31] includes a representative list of vehicles ineligible for Standard Specification.

The lower area is situated from 300mm to 375mm above the reference plane, and from 150mm to 500mm behind the rear wheel centre line. When viewed from the side of the car, no longitudinal cross section may have more than one closed section in the lower area. The upper area is situated from 600mm to 800mm above the reference plane, and from 150mm to 500mm behind the rear wheel centre line. When viewed from the side of the car, no longitudinal cross section may have more than two closed sections in the upper area. Furthermore, the distance between adjacent sections at any longitudinal plane must not exceed 15mm at their closest position. In side view, the projected area of the bodywork lying between 300mm and 800mm above the reference plane, and 150mm and 600mm behind the rear wheel centre line must be greater than 200000mm². 3.11 Bodywork around the front wheels :With the exception of brake cooling ducts, in plan view, there must be no bodywork in the area formed by two longitudinal lines parallel to and 400mm and 900mm from the car centre line and two transversal lines, one 350mm forward of and one 800mm behind the front wheel centre line. 3.12 Bodywork facing the ground :3.12.1All sprung parts of the car situated more than 330mm behind the front wheel centre line and more than 330mm forward of the rear wheel centre line, and which are visible from underneath, must form surfaces which lie on one of two parallel planes, the reference plane or the step plane. This does not apply to any parts of rear view mirrors which are visible, provided each of these areas does not exceed 12000mm² when projected to a horizontal plane above the car. The step plane must be 50mm above the reference plane. 3.12.2Additionally, the surface formed by all parts lying on the reference plane must : - extend from a point lying 330mm behind the front wheel centre line to the centre line of the rear wheels; - have minimum and maximum widths of 300mm and 500mm respectively ; - be symmetrical about the centre line of the car ; - have a 50mm radius (+/-2mm) on each front corner when viewed from directly beneath the car, this being applied after the surface has been defined. 3.12.3The surface lying on the reference plane must be joined around its periphery to the surfaces lying on the step plane by a vertical transition. If there is no surface visible on the step plane vertically above any point around the periphery of the reference plane, this transition is not necessary. 3.12.4The peripheries of the surfaces lying on the reference and step planes may be curved upwards with maximum radii of 25 and 50mm respectively. Where the vertical transition meets the surfaces on the step plane a radius, no greater than 25mm, is permitted. A radius in this context will be considered as an arc applied perpendicular to the periphery and tangential to both surfaces.
--------------------------------------------------------------------------------
Page 10
2004 F1 Technical Regulations 10 / 45 31 October 2003 The surface lying on the reference plane, the surfaces lying on the step plane, the vertical transitions between them and any surfaces rearward of the surfaces lying on the reference or step planes, must first be fully defined before any radius can be applied or the skid block fitted. Any radius applied is still considered part of the relevant surface. 3.12.5All parts lying on the reference and step planes, in addition to the transition between the two planes, must produce uniform, solid, hard, continuous, rigid (no degree of freedom in relation to the body/chassis unit), impervious surfaces under all circumstances. Fully enclosed holes are permitted in the surfaces lying on the reference and step planes provided no part of the car is visible through them when viewed from directly below. 3.12.6To help overcome any possible manufacturing problems, and not to permit any design which may contravene any part of these regulations, dimensional tolerances are permitted on bodywork situated between a point lying 330mm behind the front wheel centre line and the rear wheel centre line. A vertical tolerance of +/- 5mm is permissible across the surfaces lying on the reference and step planes and a horizontal tolerance of 5mm is permitted when assessing whether a surface is visible from beneath the car. 3.12.7All sprung parts of the car situated behind a point lying 330mm forward of the rear wheel centre line, which are visible from underneath and are more than 250mm from the centre line of the car, must be at least 50mm above the reference plane. 3.13 Skid block : 3.13.1Beneath the surface formed by all parts lying on the reference plane, a rectangular skid block, with a 50mm radius (+/-2mm) on each front corner, must be fitted. This skid block may comprise more than one piece but must : a) extend longitudinally from a point lying 330mm behind the front wheel centre line to the centre line of the rear wheels. b) be made from an homogeneous material with a specific gravity between 1.3 and 1.45. c) have a width of 300mm with a tolerance of +/- 2mm. d) have a thickness of 10mm with a tolerance of +/- 1mm. e) have a uniform thickness when new. f) have no holes or cut outs other than those necessary to fit the fasteners permitted by 3.13.2 or those holes specifically mentioned in g) below. g) have seven precisely placed holes the positions of which are detailed in Drawing 1. In order to establish the conformity of the skid block after use, it's thickness will only be measured in the four 50mm diameter holes and the two forward 80mm diameter holes. Four further 10mm diameter holes are permitted provided their sole purpose is to allow access to the bolts which secure the Accident Data Recorder to the survival cell. h) be fixed symmetrically about the centre line of the car in such a way that no air may pass between it and the surface formed by the parts lying on the reference plane. 3.13.2Fasteners used to attach the skid block to the car must : a) have a total area no greater than 40000mm² when viewed from directly beneath the car ; b) be no greater than 2000mm² in area individually when viewed from directly beneath the car ; c) be fitted in order that their entire lower surfaces are visible from directly beneath the car. When the skid block is new, ten of the fasteners may be flush with it’s lower surface but the remainder may be no more than 8mm below the reference plane.

A list of approved materials may be found in the Appendix to these regulations. 6.1.2All the fuel stored on board the car must be situated between the front face of the engine and the driver's back when viewed in lateral projection. When establishing the front face of the engine, no parts of the fuel, oil, water or electrical systems will be considered. Furthermore, no fuel can be stored more than 300mm forward of the highest point at which the driver's back makes contact with his seat. However, a maximum of 2 litres of fuel may be kept outside the survival cell, but only that which is necessary for the normal running of the engine. 6.1.3Fuel must not be stored more than 400mm from the longitudinal axis of the car. 6.1.4All rubber bladders must be made by manufacturers recognised by the FIA. In order to obtain the agreement of the FIA, the manufacturer must prove the compliance of his product with the specifications approved by the FIA. These manufacturers must undertake to deliver to their customers exclusively tanks complying to the approved standards. A list of approved manufacturers may be found in the Appendix to these regulations. 6.1.5All rubber bladders shall be printed with the name of the manufacturer, the specifications to which the tank has been manufactured and the date of manufacture. 6.1.6No rubber bladders shall be used more than 5 years after the date of manufacture. 6.2 Fittings and piping :6.2.1All apertures in the fuel tank must be closed by hatches or fittings which are secured to metallic or composite bolt rings bonded to the inside of the bladder. Bolt hole edges must be no less than 5mm from the edge of the bolt ring, hatch or fitting. 6.2.2All fuel lines between the fuel tank and the engine must have a self sealing breakaway valve. This valve must separate at less than 50% of the load required to break the fuel line fitting or to pull it out of the fuel tank. 6.2.3No lines containing fuel may pass through the cockpit. 6.2.4All lines must be fitted in such a way that any leakage cannot result in the accumulation of fuel in the cockpit. 6.3 Crushable structure : The fuel tank must be completely surrounded by a crushable structure, which is an integral part of the survival cell and must be able to withstand the loads required by the tests in Articles 18.2.1 and 18.3. 6.4 Fuel tank fillers : Fuel tank fillers must not protrude beyond the bodywork. Any breather pipe connecting the fuel tank to the atmosphere must be designed to avoid liquid leakage when the car is running and its outlet must not be less than 250mm from the cockpit opening. All fuel tank fillers and breathers must be designed to ensure an efficient locking action which reduces the risk of an accidental opening following a crash impact or incomplete locking after refuelling.

The lower area is situated from 300mm to 375mm above the reference plane, and from 150mm to 500mm behind the rear wheel centre line. When viewed from the side of the car, no longitudinal cross section may have more than one closed section in the lower area. The upper area is situated from 600mm to 800mm above the reference plane, and from 150mm to 500mm behind the rear wheel centre line. When viewed from the side of the car, no longitudinal cross section may have more than two closed sections in the upper area. Furthermore, the distance between adjacent sections at any longitudinal plane must not exceed 15mm at their closest position. In side view, the projected area of the bodywork lying between 300mm and 800mm above the reference plane, and 150mm and 600mm behind the rear wheel centre line must be greater than 200000mm². 3.11 Bodywork around the front wheels :With the exception of brake cooling ducts, in plan view, there must be no bodywork in the area formed by two longitudinal lines parallel to and 400mm and 900mm from the car centre line and two transversal lines, one 350mm forward of and one 800mm behind the front wheel centre line. 3.12 Bodywork facing the ground :3.12.1All sprung parts of the car situated more than 330mm behind the front wheel centre line and more than 330mm forward of the rear wheel centre line, and which are visible from underneath, must form surfaces which lie on one of two parallel planes, the reference plane or the step plane. This does not apply to any parts of rear view mirrors which are visible, provided each of these areas does not exceed 12000mm² when projected to a horizontal plane above the car. The step plane must be 50mm above the reference plane. 3.12.2Additionally, the surface formed by all parts lying on the reference plane must : - extend from a point lying 330mm behind the front wheel centre line to the centre line of the rear wheels; - have minimum and maximum widths of 300mm and 500mm respectively ; - be symmetrical about the centre line of the car ; - have a 50mm radius (+/-2mm) on each front corner when viewed from directly beneath the car, this being applied after the surface has been defined. 3.12.3The surface lying on the reference plane must be joined around its periphery to the surfaces lying on the step plane by a vertical transition. If there is no surface visible on the step plane vertically above any point around the periphery of the reference plane, this transition is not necessary. 3.12.4The peripheries of the surfaces lying on the reference and step planes may be curved upwards with maximum radii of 25 and 50mm respectively. Where the vertical transition meets the surfaces on the step plane a radius, no greater than 25mm, is permitted. A radius in this context will be considered as an arc applied perpendicular to the periphery and tangential to both surfaces.
--------------------------------------------------------------------------------
Page 10
2004 F1 Technical Regulations 10 / 45 31 October 2003 The surface lying on the reference plane, the surfaces lying on the step plane, the vertical transitions between them and any surfaces rearward of the surfaces lying on the reference or step planes, must first be fully defined before any radius can be applied or the skid block fitted. Any radius applied is still considered part of the relevant surface. 3.12.5All parts lying on the reference and step planes, in addition to the transition between the two planes, must produce uniform, solid, hard, continuous, rigid (no degree of freedom in relation to the body/chassis unit), impervious surfaces under all circumstances. Fully enclosed holes are permitted in the surfaces lying on the reference and step planes provided no part of the car is visible through them when viewed from directly below. 3.12.6To help overcome any possible manufacturing problems, and not to permit any design which may contravene any part of these regulations, dimensional tolerances are permitted on bodywork situated between a point lying 330mm behind the front wheel centre line and the rear wheel centre line. A vertical tolerance of +/- 5mm is permissible across the surfaces lying on the reference and step planes and a horizontal tolerance of 5mm is permitted when assessing whether a surface is visible from beneath the car. 3.12.7All sprung parts of the car situated behind a point lying 330mm forward of the rear wheel centre line, which are visible from underneath and are more than 250mm from the centre line of the car, must be at least 50mm above the reference plane. 3.13 Skid block : 3.13.1Beneath the surface formed by all parts lying on the reference plane, a rectangular skid block, with a 50mm radius (+/-2mm) on each front corner, must be fitted.

2004 F1 Technical Regulations 15 / 45 31 October 2003 ARTICLE 6 : FUEL SYSTEM 6.1 Fuel tanks : 6.1.1The fuel tank must be a single rubber bladder conforming to or exceeding the specifications of FIA/FT5-1999, the fitting of foam within the tank however is not mandatory. A list of approved materials may be found in the Appendix to these regulations. 6.1.2All the fuel stored on board the car must be situated between the front face of the engine and the driver's back when viewed in lateral projection. When establishing the front face of the engine, no parts of the fuel, oil, water or electrical systems will be considered. Furthermore, no fuel can be stored more than 300mm forward of the highest point at which the driver's back makes contact with his seat. However, a maximum of 2 litres of fuel may be kept outside the survival cell, but only that which is necessary for the normal running of the engine. 6.1.3Fuel must not be stored more than 400mm from the longitudinal axis of the car. 6.1.4All rubber bladders must be made by manufacturers recognised by the FIA. In order to obtain the agreement of the FIA, the manufacturer must prove the compliance of his product with the specifications approved by the FIA. These manufacturers must undertake to deliver to their customers exclusively tanks complying to the approved standards. A list of approved manufacturers may be found in the Appendix to these regulations. 6.1.5All rubber bladders shall be printed with the name of the manufacturer, the specifications to which the tank has been manufactured and the date of manufacture. 6.1.6No rubber bladders shall be used more than 5 years after the date of manufacture. 6.2 Fittings and piping :6.2.1All apertures in the fuel tank must be closed by hatches or fittings which are secured to metallic or composite bolt rings bonded to the inside of the bladder. Bolt hole edges must be no less than 5mm from the edge of the bolt ring, hatch or fitting. 6.2.2All fuel lines between the fuel tank and the engine must have a self sealing breakaway valve. This valve must separate at less than 50% of the load required to break the fuel line fitting or to pull it out of the fuel tank. 6.2.3No lines containing fuel may pass through the cockpit. 6.2.4All lines must be fitted in such a way that any leakage cannot result in the accumulation of fuel in the cockpit. 6.3 Crushable structure : The fuel tank must be completely surrounded by a crushable structure, which is an integral part of the survival cell and must be able to withstand the loads required by the tests in Articles 18.2.1 and 18.3. 6.4 Fuel tank fillers : Fuel tank fillers must not protrude beyond the bodywork. Any breather pipe connecting the fuel tank to the atmosphere must be designed to avoid liquid leakage when the car is running and its outlet must not be less than 250mm from the cockpit opening. All fuel tank fillers and breathers must be designed to ensure an efficient locking action which reduces the risk of an accidental opening following a crash impact or incomplete locking after refuelling.

2004 F1 Technical Regulations 16 / 45 31 October 2003 6.5 Refuelling :6.5.1All refuelling during the race must be carried out at a rate no greater than 12.1 litres per second and by using equipment which has been supplied by the FIA designated manufacturer, details concerning the manufacturer may be found in the Appendix to these regulations. This manufacturer will be required to supply identical refuelling systems, the complete specification of which will be available from the FIA no later than one month prior to the first Championship Event. Any modifications to the manufacturer's specification may only be made following written consent from the FIA. 6.5.2A cover must be fitted over the car connector at all times when the car is running on the track. The cover and it's attachments must be sufficiently strong to avoid accidental opening in the event of an accident. 6.5.3Before refuelling commences, the car connector must be connected electrically to earth. All metal parts of the refuelling system from the coupling to the supply tank must also be connected to earth. 6.5.4Refuelling the car on the grid may only be carried out by using an unpressurised container which is no more than 2 metres above the ground. 6.5.5No fuel on board the car may be more than ten degrees centigrade below ambient temperature. 6.5.6The use of any device on board the car to decrease the temperature of the fuel is forbidden. 6.6 Fuel sampling :6.6.1Competitors must ensure that a one litre sample of fuel may be taken from the car at any time during the Event. 6.6.2All cars must be fitted with a –2 'Symetrics' male fitting in order to facilitate fuel sampling. If an electric pump on board the car cannot be used to remove the fuel an externally connected one may be used provided it is evident that a representative fuel sample is being taken. If an external pump is used it must be possible to connect the FIA sampling hose to it and any hose between the car and pump must be -3 in diameter and not exceed 2m in length. Details of the fuel sampling hose may be found in the Appendix to these regulations. 6.6.3The sampling procedure must not necessitate starting the engine or the removal of bodywork (other than the cover over the refuelling connector).
