Sorry if this has been asked before but I have been reading mixed reviews on this. I'm looking into Big Brake kits ( Stoptech and Project MU ) for my 2004 Z, my question: Isn't is necessary to get both front and rear kits? I have been reading that some people have been just upgrading the fronts and keeping rears stock...

 

no its not necessary.... i have the ap racing front kit...just upgraded pads/rotors on the rear....

 

With StopTech kits, the front only kit will have the correct balance as the kits are designed with stock rear brakes in mind. A rear kit added at a later date will not shift the bias as they are designed to match factory rear torque outputs. Most other companies do not have this flexibility as they have a limited range of caliper sizes to choose from.

In the widely publicized RSX Challenge back in 2005, a Project Mu kit performed 40 feet worse than a bone stock car (171 ft) on 245 Hoosiers with a front only kit, but they may have done a better job of optimizing kits since then. For comparison, a StopTech equipped car with 225 Hoosiers stopped 60 feet shorter in the same test (110 ft), also with a front only kit.
