Upgrading to 11.75” discs on the front?

What setup did you go back with on your buddies car that you pulled the wilwoods off of?

11.75’s with factory single piston sliding calipers. Massive improvement. But again, both of his wilwood calipers had frozen pistons in one side so they were not functioning properly prior to being replaced.

Whats a good pad to run with the factory calipers

I run semi-metallics like autoxcuda. There are pads with higher coefficients of friction than that, but you have to be careful. Some of the higher performance pads also need to be at temperature to work their best, when they’re cold they don’t perform as well. The nice thing about semi-metallics is that they work the same cold or hot, which is better for a street car.
