Having a competitive autocross Lotus or a Se7en is tough with the SCCA rules. Luckily I run for fun when I run.
With the Elan I am in BS with the M3, Corvette ('63-'82), some 911 models...
With the M100 I end up in ASP because it is "not eligible for Stock Category"
It will try to do an occasional autocross with the 7. I might event have a chance to do OK if it is a tight course and I driver precisely. Another set of tires and rims would certainly help out thought.
