1) Body to be ABS or Lexan and representative of full size 2 litre stock car and no spoilers allowed.  Any car raced in real life 2 litre saloons past and present, that shell can be used. 

2) Any oval based chassis will consist of one continuous sheet of aluminium or glass-fibre reinforced plastic (composite) or carbon composite chassis that extends from a minimum 10mm ahead of the front axle line and runs continuously along the car to end a minimum of 25mm behind the rear axle line.

3) Rear pod may be may be of ally or plastic construction. It should have a single pivot point at the front and two springs to the rear with a rear guide pin, ride height adjustable rear pods are allowed.

4) External plastic bumpers to be fitted to the chassis front and rear, front to be grid and representative of a full-size stock car.

5) Overall maximum width of the rolling chassis to be 160mm (178mm including body and bumpers) wheel base should be 205mm +/-10mm.

6) Metal materials used in the rolling chassis may only be steel, brass or aluminium. Special metals (such as titanium) are not allowed. Brass and lead only may be used as identifiable weights to meet the weight limit and when removed do not have any effect on the car’s function as a rolling chassis.

7) Separate dampers are only allowed on the rear suspension.

8) Front suspension may be independent provided that the suspension design does not have any pivot rod or other mechanism that alters the wheel camber in roll relative to the chassis during its full travel.

9) Rolling element (ball) bearings are allowed on the front and rear axles.

10) Minimum weight is 1100g for both brushed and brushless.

11) Min 25mm. Max 26mm width of tyres and Max 60mm diameter no Min diameter of tyres, but the tyre must cover the wheel.

12) 3 bolt GT12/LMP style wheels are not allowed.

13) Diffs are not permitted.

14) Z drives and alloy pods are allowed.

15) Powered by either a 13.5t/10.5t brushless motor, with a 1s lipo battery esc must be in BLINKY mode with a max £150rrp or a 6 cell brushed setup with a Kamtec K21, Core21 or a Saturn 21 motor.

16) All lipo batteries are subject to a voltage test max of 4.2 volts, prior to any race at committees wishes anyone who fails the test will be not permitted to race that heat, and anybody who refuses to partake in a voltage test may also be removed from the heat/final.

17) Gearing is open both 32dp and 48dp are allowed and z drive hubs are allowed.

18) Only single bolt 12th scale wheels allowed.

19) Tyre additives are NOT allowed.

20) Parts from other manufacturers may be used as long as they serve the same purpose as the part they are replacing.

21) Minimum ride height of 3mm.

22) All added weight must be bolted to the chassis with a nut and bolt except under lipo battery weights. 

23) All cars must be commercially available to buy. Any one wishing to manufacture a car must go through the process of test and development at their regular club with the clubs agreement. If they wish to then race the car they must be able to make units available to purchase by other racers. It must comply to the current construction regulations if being sold to race. It must be of a comparable price to those being sold by other manufacturers and not overly priced to limit availability. Anyone wishing to develop or modify a car that does not comply with current construction regulations has to do that test and development at their local club with their agreement. Any changes to the construction rules that allow new designs to race would need to be approved at the BRCA AGM following the correct procedure.
