Does anybody have these on their monte? Ive had them for about three years now, they're good, but i need new 13 inch rotors and wanna find out where i can get the rotors at other than zzp. Like maybe a specific vahicle has these 13 inch rotors? with the same bolt pattern? Anyway to find out? I emailed zzp a while ago and they didn't tell me because they wanted me to buy them from them, but i don't think their rotors are all that good.

 

i was just going to ask if they were the brakes off of the gp gxp, but your title says there cast iron, and i dont think that the gxp ones are iron. you might want to check into that though. i doubt that zzp came up with there own design.

 

I went to a local o'reillys earlier today and talked to a person that worked there, he was pretty cool and was sure that the rotors are the exact size as they are on the grand prix GXP. So he took one out and we compared them side by side, and lo and behold, exact same, 12.71 inches, same bolt pattern and everything, now i can finally get some drilled or slotted rotors instead of buying them at zzp (a little to expensive)
