Correct as of 1st January 2019
The specifications have been updated to clarify what can or cannot be done within the formula for 2019.
This formula is designed to encourage new drivers to our circuits, to enjoy the atmosphere & thrills of driving on an oval, without the substantial financial ongoing investment. It also gives the opportunity to race to those drivers who cannot give the commitment necessary to compete at the very high level of all our other Formulas.
Mini Super Twos reserve the right to amend the rules at any given time without notice. They are intended for the sole recipient and not for distribution. Drivers and officials will be notified of any changes immediately.
Rules are there to be followed. If you are not happy with the rules PLEASE DO NOT SIGN A LICENSE FORM.
The object is to complete the specified number of laps in the shortest time. No hitting of parked cars, cutting the corners and no deliberate drivers area contact. You may push a car from behind to move it off line but spinning a car or any deliberate fencing are strictly not permitted. Attacking a car from, or on the infield area is not permitted.
Actions deemed to be deliberate or dangerous will carry several different types of penalties, this may be being loaded up, a three month ban, banned for a year or even a life time ban.
Racing is in an anti-clockwise direction on a clearly defined circuit with a separate infield. Any wheels passing over the demarcation lines or entering on to the grassed infield areas will mean that the driver will be penalised.
Violations
- When referring to the engine, final drive, mechanical or construction Rules & 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 the Standard Parts in any way.
- It is the responsibility of the Driver to prove to the Promotion that the part is legal, by way of written proof of where the part originated. This must be undertaken within 7 days, otherwise the item in question will be deemed illegal, resulting in immediate suspension from racing & referral for disciplinary action. Unless the rules say you can do it, you cannot do it!
- Presentation of a Vehicle for Scrutineering is a declaration by the entrant that the vehicle is eligible for that event.
- Car engines & fuel will be checked on a random basis. Violations or refusal to allow an engine check will result in an immediate suspension of all racing facilities.
- Should a discrepancy occur between the Specifications then the Promotion will exercise its judgement, and that decision will be final.
- Clarification on any one item may be sought from the Promoter.
- Each driver is permitted one car per meeting & each car is permitted one driver per meeting.
