As I think I mentioned, there's much more to handling than "stiff and stiffer".

If your goal is to have a FWD car that handles as well as possible at Sebring... both Jeff and I can tell you from experience that "too stiff" won't get you there. Sebring is bumpy. (as are many other tracks) In fact, some of the fastest turns that can have some of the most significant impact on lap times are VERY bumpy.

Don't just assume that you want the stiffest front and rear bars and the highest spring rates. If you want a car that truly handles well, that's not what you want.
