I used RSM rotors for awhile. They're * H I T for quality and their customer service is worse. When I warped them for the second time, I went with Powerslot (these are made from Brembo blanks and even say 'Brembo" on them). I warped them lightly once, which I believe was due to the rears not doing their part. I've since had them turned, and replaced the rears (total replacement) with NAPA premium components. I'm happy again. The powerslots on front coupled with Raybestos quiet-stop ceramics add a noticable amount of braking. Coupled with the good rears (which I just re-adjusted yesterday), I have good braking again. Much better than OEM.
The Powerslots and ceramic tend to bite harder when they get hot, rather than fade. Be advised that you MUST be anal about your wheel lug torque if you intend to protect this investment in your brake components. Cleaning the threads of the lug studs and lugs very well and lightly lubricating them before torquing, then torquing in stages (50, then 75, then 100 in a star pattern) is VERY important, at least for the front. Our cars are under-braked (87-99), and need all the help they can get.
