Stoptech Brake Rotor Replacement
Since Stoptech is no longer in business, are there alternative or compatible rotors for ST60 / ST40 calipers? Rotors are 355mm x 32mm.

Hmm - good question. I did a little hunting around and the info is spotty. I'll suggest you call Buybrakes.com and talk to John Butler, he was a Stoptech dealer and has a lot of general industry knowledge. I bet he has a solution for this.

Depending on offset, those rotors sound like a C6 Z06 spec.
edit: sorry, didn't realize those rotors were two-piece.

You can get replacement rotor rings from Girodisc.

I know that BimmerWorld has helped one of my fellow racers match up rings for his Mustang as well.

Aha! Now I know why the slotted/cryo-treated rotors I use on my SUV are no longer listed on the Tire Rack site!
