Gt500 Rear Disc Conversion
 

I am looking at rear gt500 discs, any advice on which brand to go for. Ford oem and centric premium seem to be a good value, which is better?

I put a set of ford oem ones on earlier this past season. They have about 1200 track miles on them with minimal wear, no surface cracking.

I had a set of centric rear rotors last season (11.8's not 13.8's) and they both had significant surface cracking after a couple hundred track miles then ended up having a propegating crack in one at about 700 miles.

I've used oem and centric front rotors as well and oem seems to hold up better. I'd go oem

Thanks for the info I will try oem.

Just ordered ford oem gt500 rotors. Is it ok to use my existing hawk hps pads? I know they will fit and it is ideal to use new pads on new rotors but I do not want to shell out for a new set of pads when the existing ones have plenty of lining.
