Chumpcar's lack of performance rules and car rules are why some of those teams are interested in SCCA.
Chumpcar came to start as a result of SCCA rules and regs, along with track time cost .( as well as down time over the weekend for 2hr of track time.This last part we will need to address in the future ).

So to address this large market ,we should address the shortcomings of Chump. ( AS chump has addressed the shortcomings of SCCA. )

1) Lack of classes, along with allowing the E 30 and 36 to race heads up with the little real 500$ cars .
The above classes address much of that. One class will not work for any long term . The little cars will stay home, as they are doing now in Chump.

2)lack of tire size rule, same result , big power can be applied .

There is a market for these cars with some loose rules to have a good time in SCCA.

They spend a lot of money to run Chump. Many teams would have a few races with SCCA. Many SCCA cars can run Chump also..
