We run Dynalites on the race car, with different rotors, they work incredibly well (circle track). You really can't go wrong with a Wilwood kit. I'm going to be using the Dynalite calipers on my car, but with a custom disc hat setup and rotors. That's not a bad deal though, my setup is only slightly less expensive. If you want to use Dynalites on the rears, PM me, and I'll tell you how I intend to do it on mine.
