5.5.1 Unrestricted except that the use of carbon fibre composite structural materials is prohibited. No engine oil or water tubes are permitted within the cockpit. The engine will be mounted upright and aligned fore and aft in the chassis.

5.5.2 It is the intent of these rules to minimise the use of ground effects to achieve aerodynamic down force on the vehicle. Thus the chassis and body surfaces which comprise the underside of the car shall not deviate from a flat plane by more than 2.5cm or 1”. This deviation may not be used to create an aerodynamic device. For this purpose the underside is defined as being within the rectangular area along the length between the front edge of the front tyres and the rear edge of the rear tyres and across the outside of the front and rear rims. No aerodynamic devices e.g. skirts, body sides etc., shall extend below this surface anywhere on the car to the rear of the front wheels. The area of this surface must extend to the full width of the body, it must be of minimum width 142.24cm over a length of 91.44cm (i.e. there must be a rectangular solid surface of at least 142.24cm measured across the vehicle by at least 91.44cm measured along the longitudinal axis of the vehicle).
The soles of the feet of the driver, seated in the normal driving position and with his feet on the pedals in the inoperative position, shall not be situated to the fore of a vertical plane passing through the centre line of the front wheels.

5.5.3 The chassis must include an impact-absorbing structure ahead of the front bulkhead of the main structure. This structure must be solidly fixed to the extremities of the bulkhead (i.e. with at least 6 bolts of high quality steel of 6mm minimum core diameter requiring tools for removal). Or it may form part of the chassis structure. It must constitute a box of 30cm minimum length, 15cm minimum rearward height and 400cm2 minimum total cross section. The construction material must be metallic and it must be designed to give protection to the driver by way of calculated deformation and controlled deceleration in the event of an impact. The manufacturer may be asked to supply information to the eligibility scrutineer (or his representative) to confirm the design calculation and/or any impact testing carried out by an approved test facility. Irrespective of the size of the impact absorbing structure (safety foot box), the maximum total area of access holes allowed in this structure shall be 300 cm2. The basic structure is defined as a unit with 5 closed sides, and 1 open side. The access holes dimension quoted apply to any modification to the 5 closed sides.

5. 6 BODYWORK INCLUDING AEROFOILS.

There shall be at least 25cm (9.9”) wide foot space for the driver measured at the pedals. The passenger space should provide as much seat space, elbow room, foot and leg room in terms of length, width and height as that of the driver space. Battery boxes and fire extinguishers are permitted in the passenger seat area.
v) All ducted air for heat exchangers (water/oil) shall pass through those heat exchangers.
vi) Maximum vehicle length forward of the front axle centreline: 91.5cm (36”) (including aerofoil/spoilers), the maximum vehicle length rearward of the rear axle centreline: 115cm (45.5”) (including aerofoil/spoilers)
vii) Aerofoils and/or spoilers mounted at the front of the vehicle are permitted. Those aerofoils and/or spoilers may only be adjusted in a horizontal plane.
ix) Adjustable spoilers mounted at the rear of the vehicle shall be in the form of a flat plane and may only be adjusted within +/- 20° of vertical.
x) The aerodynamics may be modified by the addition of a wing only in the form of SRCC authorised Part number: SRCC-RA1, defined in Appendix B The following rules apply to the mounted wing:

(a) Only engines with a Ford Power Products Identification label carrying its unique FPP serial number are eligible. In addition, each engine will be stamped on the block with a DPP serial number. These are to be positioned as specified in Appendix C.
(b) Engines will be mounted upright, and aligned fore and aft in the chassis.
(c) The addition of any material, be it metal, plastic, or composite etc. by any means be it welding, bonding, encapsulation or encasement to any component is prohibited. However, specific repair of the mounting points of the cylinder block to the transmission or chassis is allowed, whilst other casting repairs may be allowed with prior written approval of the Eligibility Scrutineer responsible for the Formula.
(d) Balancing of reciprocating and rotating parts is permitted only by removal of metal from locations so provided by the manufacturer as detailed in Appendix C.
(e) Water pump and generator drive pulleys and their retention bolts, washers and belts are free.
(f) Mechanical tachometer drives may be fitted.
(g) The use of non-standard replacement fasteners, nuts, bolts, screws, studs and washers which are not connected with, or which do not support, any moving parts of the engine or its compulsorily retained accessories is permitted. Freedom granted to any fastener does not allow for freedom to move items relative to each other. For components that are granted the freedom for the fitment of a key or dowel, then material may be removed to allow the fitting of the key or dowel. Only one hole or keyway per component is allowed.
(h) The use of thread locking compounds is permitted.
(i) Gaskets are free except for the cylinder head, intake and exhaust system gaskets which must be standard Ford manufacture for the engine.
(j) Any process of cleaning may be used on any component providing the surface finish, which must remain standard, is not affected.
(k) Forced induction is prohibited. Ram air effects generated by the forward motion of the car is not considered as forced induction.
(l) The expression "Standard", "Standard production" or similar expression is deemed to imply that the part has been manufactured by Ford, or a Ford Motor Company Ltd. authorised sub contractor, for specific use on a specific model of the vehicle or engine. Consequently for these rules only parts manufactured specifically for the Ford 2000cc, 16 Valve engine (Duratec DHE 420) in its 145PS form, may be used. Any machining marks on cast components resulting from manufacturing procedures will not cause disqualification. Only machining and component preparation carried out by Ford Motor Company Ltd., or by a Ford Motor Company Ltd. authorised sub-contractor is allowed unless otherwise specified. Any production deburring or imperfection removal during initial manufacture may not be modified or extended. The Scrutineers decision will be final (based on advice from Ford Manufacturing) if a dispute arises regarding the amount of tool, or other marks that are evident in any particular component.
(m) The exterior surfaces only (of the complete engine assembly) of ferrous parts and the exterior surface of the aluminium cam cover may be protected by paint or similar means. No internal component or surface may be coated by any protective finish. Other Ford produced aluminium components may be protected only on their external surfaces by a transparent clear varnish, or similar. No rework may be carried out on any component unless specifically authorised by the regulations. The engine and associated parts must remain exactly as produced by the Ford Motor Company unless expressly detailed in these regulations. If the regulation allows a change, then that authorisation would allow the change to be carried out. However any statement defining minimum weight or dimensions does not grant permission for rework to obtain these minimum values, unless carried out in accordance with these regulations. Only Ford standard parts (parts manufactured by Ford or a Ford Motor Company authorised sub contractor) specifically for the 2000cc, 145PS version of the Duratec DHE 420 engine can be used in this series. No treatment that alters in any way the surface finish, hardness, or other property of the original production component is allowed. The only exception to this is any deposit derived from the lubrication and combustion processes naturally occurring during the running of the engine. Ford reserve the right to prohibit the use of specific components introduced as Production changes, if in the opinion of the Ford Motor Company Limited, they are deemed to have a performance advantage. If in doubt contact Ford Motorsport or the series scrutineer.
