This is a beginner class and I want it to stay that way. Rules are going to stay simple, Safey first, and I will be inspecting these cars for that. If there not safe, they will not race. With that out of the way, these cars must remain stock in all areas except gutting the car of the interior and all glass. Motor must remain stock
Transmission must remain stock
No locking of front end
No racing shocks of struts or springs
No computer chips
No racing tires or wheels
No supper charger
All four tires must be the same size

4 cylinder cars only
This is just basic rules for now, but this should be enough to get you started on a car build.
A easy way to look at it, if it didn’t come stock on the car from the factory. Then it’s not legal.
With the price of everything going up, I want this class to stay as affordable as possible. Hope to see y’all this coming season. Get you and some of your buddies and start putting y’all some cars together, and have fun with it. In all the years I raced cars, I have way more memories of nights working in the shop with the guys and the road trips back and forth to the racetrack than I got racing.
