RSM'* warped, had them turned, warped 3 months later. Keep in mind they stop like MAD, especially in the rain, and didn't warp for 6 months, despite my aggressive driving and braking.

Powerslots are still in the box, but the slots aren't nearly as deep. Interesting, since the RSM'* with deeper slots tend to build up material in the slots. Not sure how this will play out long-term.

I have SP Performance rotors in my car; they both drilled and slotted too. Have not experienced any problems for over a year. Also, I had them cryonegically frozen, including the pads, new rear drums and shoes.

I really liked my PowerSlots...... I wish I bought them the 2nd time...

They did however warp after a year.... :?

What kind of pads did you use? I was thinking about powerslots but certainly don't want them if they can warp in a year. I got a full year out of my stock rotors and ceramic pads last time.

I was using just regular pads.... but now I've got ceramic pads.
