ok guys i just read about every post ever about upgrading to 300zx tt brakes. Here is what i want to know. It seems to be that people say if i upgrade the fronts w/ stock rears, i will have a bias problem. What happens if i do all four corners w/ lines and the tt m/c? do i still have a bias problem? It seems to me that i wouldnt because that is the setup in the 300zx and i dont think nissan would make a setup with a bias problem. please inform me if i am wrong. also, what if i did it with all four corners upgraded and left the m/c stock. i shouldnt have a bias problem then right, just other problems like soft pedal and would that cause them to lock up easier? sorry, just got the calipers and dont want to spend any more money if the upgrade if b/s.
