Left cracked rotor, right brand new OEM rotor

I think the uncracked one is the OEM, look at the cut off for the grey coating, it's paint free inside that where at the cracked R has the black coating inside that. More reason for me to stay OEM unless I eventually go floating rotor setup, which I'm not sure is really worth it.

I will definitely go with the floating rotors next year for the track.

WTF has been shoved up your ass? Seriously go to the Facebook groups you'll fit in there better. It's getting annoying seeing your mostly negative comments and you don't even like your car so just move on.

A lot of sticky weights on that rim bro. Good god. Solid rotors are not better than drilled ones for stopping on the track. That's ridiculous. Buy some expensive drilled or slotted rotors and some better pads and you won't crack them. For metal to come apart like that from heat, tells me your rotors are cheap and don't dissipate heat at all.. all the high end sports cars I've ever seen have drilled rotors. I'm sure they have it right.
