Are there any other alternatives other than the HP kit? I have seen 300ZX TT brakes on a P10, but it looks a little hard. How would you trim 3mm off the diameter of a rotor? Will the G20 brake lines work with 300ZX TT calipers? Lastly, will the stock master cylinder be large enough or would I need one from say a Altima? Any help is greatly appreciated. If anyone has done any brake modifications let me know.
