Ok so I need a lightweight front brake set up for my car....drag....Id rather keep the stock caliper if I can. Anyways, I know guys switch to the GT brakes but what is required? Rotors and caliper? How does the caliper bolt up? Can I use 14in 2 piece rotors and just remount my stock caliper? I want new rotors, but I'm buying a lithium battery so I don't want to spend 1500 on a pair of rotors. If all else fails, I'll just get the willwood front brake kit since that's only 800. Any help will be appreciated.
