bgrd,

My Nova was a budget bracket racer and I really enjoyed it. Sounds like your car is all tubbed out, I assume with a full cage. With a tall tire like that I definitely think you need a deeper gear. Unless you have a lot of lightweight fiberglass pieces I would estimate your weight to be more than you think. My car was all metal, with a 6 point roll bar and subframe connectors. The interior was stripped except for a single fiberglass seat. With me(160#) aboard it weighed about 3000 pounds.

As you are experimenting, I suggest only changing one thing at at time so you know for sure what makes improvements.

Do you have a transbrake?
