When i did HPDE's at VIR and Summit Point i had my stock braking system with the porterfield pads, oem brembo vented rotors, and racing brake fluid. i didnt have much power basically stock KA with speed limiter removed. i never had any brake fade going 130mph on the back stretch at VIR going into the braking zone and braking late. worked great. didnt run any kind of cooling ducts or anything. after a two day weekend at the track with 4+ hours of track time i never had any problems except with the car shutting off when going into the braking zone... lol was a error reading on the ecu that caused it to shut down... dont know, never figured that one out. lol
anyways, now that im actually making power lol, ive upgraded to z32 front calipers. im running the stock master cylinder. ive had to readjust my brake foot a little.. so i wont lock em up... but they have worked fine. still, im running the porterfield pads and they are just amazing.
also, redrilling rotors is stupid. makes the rotor weak and can cause cracks. that would suck.
