Our rules are continously evolving and we will look at them each meeting, the aim is to have fun and enjoy ourselves, Please keep washer size to scale, and overbuilding to a minimum.
Other formulas will be invited to our meetings at Freshfields Raceway to compete at meetings and they will have their own Tarmac Championship races . The 1/12th alloy bangers and 1/12th abs bangers will join the 1/8ths for their own Tarmac World Finals .
As these formulas are not Hooked Racing formulas we do not publish a set of rules for them but we will do our best at the meetings to check over cars that should be built to Guildford RC / KCO guidelines. In the 1/12th alloy class special attention will be paid to any overbuilding or over the top repairs and any cars that are deemed to be overbuilt will NOT be allowed to race .
It is important for all visiting formulas to follow our racing guidelines .
Racing is in an CLOCKWISE direction at all times.
No marshalling is allowed at Freshfields raceway and you must stand behind the outer barrier at all times – you are only permitted onto the track when all cars have come to a halt.
No going past the marked lines wrong way down straight, you are only permitted to turn around in the marked zones and being on opposite outside the marked zone will mean a black flag. There is no going on opposite on either straight , if spun on either straight you must you must turn your car and proceed in the correct racing direction immediately.
If a car is touching the inside wall, it is deemed as on the shale/Safety area, no deliberate hitting a car in the safety area.
If a black flag is pointed at your car during a race you have been deemed to have broken the racing rules and must pull your car into the centre / safety area immediately . If you continue to race after a black flag you will be loaded for the rest of the meeting .
At the end of each race a red flag will be waved you must bring your car to an immediate stop . Any hits after the red flag will see any points you have scored in the race removed and you will be loaded.
