STS2 rules are the same as STS except for the basic eligibility requirement. STS2 is for 2-seater cars with something like under 1.9 liters displacement.

I was already illegal for STS2 before with my intake and LSD. With my new aluminum flywheel and non-stock clutch, I think I'm too far gone. I wouldn't feel right running in the class. (even if I did beat nunyo)
