hay all whats a good up grad for my s13 rear diff and all like calipers ect i herd 300zx stuf is good what sugestions do us have..?????

One of the best and easyest things to do is use R33 brakes and hubs(this will make it 5 stud)


then get a 2way lSD for the r200 diff

Why do you need to upgrade rear brakes?? Is the car n/a or turbo?? R200 or R180 diff? If it's an R200 diff, 2ways are very easy to get. Brakes are fine. Unless your car is high powered, standard s13 brakes are sufficient.
Diff, coilovers, radiator are your most important mods.
