No. I am asking for a better solution than 'ban the sports cars' in a power-to-weight class.

More weight% difference?
Wheel width allowances?

I don't know but I'm not going to do the homework here. Throw out some real suggestions and lets slice 'em and dice 'em.

There is actually more at play here than just chassis. Isn't there some concern that the K20 can make more power than intended? So you throw one of those into a Civic and it can run with a Miata so now we have to limit both. Throw one of those into an S2000 and you have a double-edged sword.

I still think the class is to young to make a drastic change. Keep tweaking.
