I would definitely go with the Wilwood or the Stoptech kits before even thinking about that goofy SSBC caliper. AND, it's only a 2-pot caliper instead of the 4-piston that you get with the Wilwood and Stoptech kits. Also, the SSBC kit has a one piece rotor vs. the aluminum hat 2-piece in the Wilwood setup. Try and find any SSBC calipers on some race vehicles.
Just my thoughts.
