I have Powerslot Slotted and Cryo treated rotors with Hawk HPS pads.
www.buybrakes.com is where I got them.
Had them for just about 15,000 miles. I checked the pads on my last oil change/rotate and they are still about 1/2" thick.
I bought them mostly for bling. I guess I'm having withdrawals from having a sporty car. ATE makes a trick looking set of rotors for Tacomas.
I took extra care and made sure they bedded in after I installed them. I have put them through hell and they have not "warped".
I even locked them up once while avoiding an accident. I thought for sure they were done for. They smelled bad but they did not "warp".
I have driven them through one stream (7 oaks), a day at the dunes(parker), a day in the snow(mammoth), numerous mountain trips to the snow(but not really IN it mammoth, wrightwood, bigbear, 7 oaks). Not to mention daily LA stop go traffic.
My oem pad/rotor set up "warped" and would fade when driving mountain roads. It would fade pretty bad. I could feel it sometimes when in bad stop go traffic too. I think they were "warped" from the previous owner though.
BTW: Rotors don't warp they develop high and low spots from the rotors wearing away quicker in some spots more than others or from built up brake pad material that is stuck to the rotor.
And in my opinion a good pad/Blank Rotor(oem, Brembo, even Autozone)/Brake Fluid combo combined with proper instillation and bedding in will perform as well as any slotted set up. Good brakes are more in the pad and fluid than in the rotor.
