Great thread. I was reading through this early this morning on my flight home.
I'll update the Bilstein thread with the new (changed) part number.
To answer your question ""What can I get in to, or ride, that will give me an idea of how each setup combination will ride?"
There's really only two ways to get that experience. 1) get into one of our cars who have either setup or 2) get into a Mustang Cobra Convertible.
Oh, and BTW, you're welcome for the ShockWarehouse referral.
