This formula is NON-CONTACT and cars should be prepared with a professional racing appearance.  This standard is required to be kept up throughout the drivers racing season.  Cars with tatty, dented and badly battered panels will not be passed by the scrutineer.  (Metal panels only may be used the exception being front and rear bumpers).

When referring to the engine, gearbox, differential, mechanical or construction, rules and regulations the principle will always be: Unless permission is specifically granted to make modifications, or any variation, nothing may be done to alter or change in any way the standard Parts.

Unless these rules state you can do it, you CANNOT DO IT.

Cars, Engines and Fuel will be checked on a random basis.

Violations will result in an immediate suspension of all racing facilities and any refusal will also result in an immediate suspension.

All car and engine specifications will be taken from either the manufacturers technical specification books or the technical service data books for cars, as published by Glass’s Guide Service Limited.  If there are any discrepancies occurring between books, the promotion will exercise its judgment, which will be final in any dispute. 

N.B. Drivers are reminded that scrutineer checks can be carried out at any time, and most certainly at official championships.  If parts are suspected of being illegal make sure you leave them with the promotion if you do not agree.  If you refuse it will automatically make the parts illegal.  It is the responsibility of the driver to prove to the promotion that the part is legal by the way of written proof of where the part originated.  This must be done within seven days, otherwise the part(s) in question will be deemed to be illegal and will result in immediate suspension from racing and referral for disciplinary action.

Any Saloon or hatch back type car of steel monologue construction, of which the overall length and width of the unmodified car does not exceed 13ft 7in by 5ft 6in.Cars may be front or rear engine and front or rear wheel drive but may not be converted between front wheel drive and rear wheel drive. Four wheel drive is NOT permitted.

All cars up to 2000cc will race under the same banner.  The only cars eligible for use are those set out within these specifications and they must be raced with mechanical and constructional specifications as produced when new with the original engine capacity not exceeding 2000cc 8v. All constructional rules will be the same for all cars up to 2000cc 8v.  Any fuel injected cars will have to use carburetor and manifold within their range.

Any engine up to 2000cc 8v maybe used, any 16v engine up to 1400cc may also be used, engines must be as produced by the manufacturer, two valves per cylinder. Engine mountings to remain standard, with the exception of Front Wheel Drive cars where the top engine mounting (by valve cover) may be solid. 

Cylinder Block.... Nominal overboring to a maximum of 0.090" is permitted.  Skimming of the block on the head gasket surface only is permitted.  No other modifications to the block are permitted. 

Cylinder Head.     The skimming of the cylinder head on the head gasket surface only is permitted.  Cylinder heads must remain standard and un worked. A 3-angle cut, is permitted but there must be no machining or fettling either side of the valve seat.  The valve length must remain within standard manufacturers tolerances (i.e the length as supplied to the industry, not a minimum service length). Eg. Vauxhall 104.25mm-105.35mm, Inlet Valve diameter 33mm and exhaust valve diameter 29mm.  Valve springs are free.  The following must not be machined, repositioned or modified in any way: valve caps, collets, valve guides, spring seats and valve stem oil seals, with the exception of Corsa/Nova lash caps which may be of competition type.  Solid lifters may be fitted.  Hydraulic lifters may be welded or modified to be solid and shimmed. 

                            If the oil feed to the cylinder head becomes miss-aligned when head is surfaced it may be re-aligned.

i)                    Head bolts may be shortened or washers may be used.

ii)                  Bronze valve guides are NOT permitted unless fitted as standard, but it is permitted to use a thin wall bronze sleeve in existing guide.

Unless stated above, no metal may be added to suspension parts.

Rear axle locating rods must remain standard length and bushes as original.  For vehicles fitted with a rear beam axle, any repairs carried out to the rear axle beam should be done by simply resetting the beam with hydraulic equipment, always within the manufacturers tolerances.

No competition shock absorbers are allowed on the rear.

The use of quick release steering wheel mechanisms is permitted.  Steering rack arms may be modified i.e. the nearside arm may be lengthened and the offside arm may be shortened.  The steering rack must occupy its original position, but the steering column height may be adjusted to suit the driver.  It is recommended that the upper retaining bracket of the column be strengthened on some cars for safety.

To be as original and to work on all wheels.  Handbrake is compulsory.  No biased braking.  No modification to brake compensator(s).  No hydraulic handbrakes except where standard.  No competition parts with the exception of competition pads may be used.  Brake components from the same manufacturer’s range may be used, but must be done without modification of standard parts and may not be from a larger cc vehicle e.g. no parts from a 1600cc may be used.  For front wheel drive cars fitted with load dependent brake pressure regulating valves, the valve must not be modified, but the connection from the suspension to the valve may be adapted or removed, and the regulator lever arm secured in any position.

To remain as production with removal of inner door panels and the inner rear quarter panels from the waistline down being permitted.  Removal of structural stiffeners is not permitted, with the exception of boot and bonnet.  Wheel arches may be cut away to accept a wider rim.  If the body is cut then 2" wheel spats of mild steel must be fitted.  Seam welding is not permitted anywhere on the car with the exception of the doors.  Tack welding is allowed - this is defined as being 2" weld with a 6" gap before next weld.

No strengthening may be added, but on cars where suspension mountings or subframe locate on a weak part of the body suitable strengthening may be added.  All doors must be fixed when racing.  No spoilers or aerofoils except where fitted as standard to the make and model of the car.  Mild steel panels only may be used, door skirts may be fitted but these must tie into the lower edge of the wheel arch and must not be deeper than 2”(50mm).  The width of the skirts must not be wider than the wheel arch.  A single 2" diameter inspection hole must be included in bumpers on the driver’s side.  Holes are permitted in side skirts but must be equal on both sidesSide skirts may have holes.  Gusseting of the near side front and off side rear wheel arch is compulsory.  Gusseting is permitted between the centre line of the front and rear axles, where the side skirt joins the wheel arches.  Cars fitted with integral rear panel and bumper may substitute them for a metal panel of original shape and size.

Any replacement panels must be of the original gauge with a single 2" diameter hole drilled for inspection.  Front panels must not exceed 1.2mm (0.048) or 18 gauge.  Holes are permitted in the front panel between the headlamp apertures for cooling purposes only.  Where two sections are used to form a front panel, the overlap must not exceed ½".  Repairs to front wings and flitch panels must be carried out with material of original thickness, not 18 SWG.  Where front panels are non-original of 18 SWG, only the front section may be of that material; the "wrap-around" section to join it up to the wings and the inner flitches etc. must all be constructed with the original thickness of material which is usually 22 or 24 SWG.  Where front panels are non-original, the shape reproduced must be the original silhouette of the car when the original bumper is removed.  Front panels must not incorporate a front bumper in the shape produced.  Likewise the flitches must follow approximately the original contour, not folded with angles to provide strength.  Where bonnet slam panels are replaced, lightweight tube or box (2” x 1” or 1” x 1” with 1mm or 1.5mm wall) must be used.  Cross ties must be 16- 18 gauge, 1mm wall box section.  Panels must not be doubled.  Where headlamp apertures are filled, they must not have more than a 1” overlap.
