MOTOR SWAPS in MOD UTV
After input from many, many, sources I have made the final rules update for the FORMULA DESERT LITES UTV classes. I had a super stock class exactly as BAJAXP proposed, I dropped it but might put it back in if interest was strong enough. I am allowing motor swaps in the SUPER MOD CLASS and have a class for the smaller UTV's with the MOD LITE. Look these over and tell me what you think. Better yet come to the race on December 18th and take part in the beginning of something that will grow into one of the best series for UTV's. The ACR's for safety etc are below the Class Rules.
