Genuine StopTech or not?
I had a cracked rear rotor. I posted some pics of it here. Someone postulated that they were not "true" StopTech drilled rotors.
Well, what do you guys think? Are there any casting marks on the real thing? I can find no casting marks on these. They came in boxes marked StopTech, they had instructions that said StopTech and there was a sheet with instructions for "bedding in" the new rotors and pads.
I just had the OEM rotors machined and put them back on.

check stoptech's website or call them and ask them about drill design.
the one's on stoptech's website have a different drill pattern, but not sure if it's a generic drilled rotor or one specific to the G application.
based on the picture from their website, that does not appear to be a genuine stoptech rotor

Sorry to bump this, but i recently bought Stoptech rotors and the pictures that OP posted don't look like StopTech's. The rotors that were posted on the 8th post look like the ones i have. It really sucks that the rotors cracked tho.

Nope they are made by Centric which I found out is the Parent company of StopTech.
Here are some of the emails I got:

Hi William, Centric Parts owns StopTech, we are the same company. That is why the rotors say “CENTRIC” on the edge. We have had no other issues to my knowledge with X-drilled rotors on the rear of street driven vehicles. Let me discuss this with Engineering on Monday and see what we can do.
How long have they been on the car and where did you purchase them? Crossdrilled rotors tend to crack in high heat conditions, but the rear of this car is not considered high heat, unless its been on the track
Hi William
What kind of use has this car seen? Any track days? Unfortunately, this is a characteristic of Crossdrilled rotors used in extreme heat or heavy duty applications. Because of the tendency of crossdrilled rotors to end up like this under heavy use, Slotted rotors were developed, and if the car is used in any manner aside from normal street driving, slotted rotors would certainly be the best choice.
Thanks,
