Classes and Rules
General Rules:
There will be no tents/EZ ups allowed this year except for vendors.
No Gyros or driver assist allowed. If at any point you are found to be using it you will be disqualified from the event.
If the rules do not say you can, then you can't.
If you THINK you can, you should probably ask.
We will not be responsible for transponder failures
Official's decision is final.
Tires:
Tires and inserts must remain unaltered as they come from the factory. Jconcepts tires can have their tread ground down. Sidewall stiffeners are not allowed. A Main cars might have their tires cut open following the race for inspection.
Batteries:
Cars will have to go through tech for voltage each round. Maximum voltage allowed is 8.44v. Racers who present vehicles at pre-race tech with a battery voltage up to 0.02v per cell over 8.44v will be given one opportunity to reduce the voltage or to replace the battery with one within the voltage limits. Racers must leave the inspection area and rejoin the inspection line while replacing batteries or reducing voltage. In no case will the start of a race be delayed due to a racer using this provision. Racers who present vehicles at pre-race technical inspection with a battery voltage greater than 0.02v per cell over 8.44v will be disqualified from that round of racing. Racers who use the option of reducing voltage or replacing the battery and fail on their second attempt will be disqualified from that round of racing.
