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.
Exactly. I have been thinking about switching back to the stockers for a while since Im still running a stock KA. Or doing Z32 rear brakes and seeing how that works with Q45 fronts. Im not sure if that would give it too much rear bias though.
Q45's have done me well so far, and I loved them up in the mountains, but normal driving I've locked up more than I would of liked too.
I'll have to put more thought into it when I get my car back on the road. Is your car a fully weighted S13?
