Just wondering if many people have changed their rear discs.

Debating changing mine as I'm changing the fronts to Project Mu.

Rear ones - Should i also change to project mu if changing?

 

don't bother. unless it's a 2-piece vented rear rotor, they're all the same. I wouldn't pay a premium for a brand name rear rotor if it's still a solid non-vented rotor.

Look into the rear rotor from Urge Designs if you're looking for a true performance upgrade for your rear rotor, otherwise, just buy a Centric or StopTech rear rotor (which ever is cheaper).

if you want to be anal about having matching slots compared to the front rotors then go for it. otherwise just use cheap rears like centrics. I personally skimp all the way to C-Teks for mine.
