I have had thes rotors on my car for about six months.I just wanted to let everyone know if they work or not.Normal driving in the city and highway they work way better than stock.They don't heat up very much during 80-0 braking.However,they are not very good after that.After braking from 125-60-0 the heat up really bad and after they heat up your brakes are pretty much useless.I haven't warped them YET and other than high speed braking they are very good.

Thats my review of the stock diameter powerstop slotted rotors.

Any questions?

what pads u run?

I've had powerstops for about a year, with axxis m/m pads - front and rear. I've had them turned once - about 6 months ago.

I drive on the interstate daily. Running at 80 then stepping on the brakes hard, the car pulses really bad. So it's time again.

Regardless what brakes you buy, they can warp. I have a feeling cold rain on hot brakes does it. Once you have to turn them, expect to turn them every 8-12 months.

Someone might disagree, but that's been my experience.

I was also wondering what pads you were using where you'd get fading.

Also, I don't think most people are going to go from 125 down to 0 on a regular basis with their cars :)

I used my powrslots with porterfield R4S pads when autocrossing, and the brakes didn't fade at all, even after repeated runs.

I have the $60 brake pads from Raybestos.The ones with ceramic in them.I can autocross all day long and they don't fade at all.It's just high speed braking when I notice the brakes fading.I can run from 60-0 all day long(exaggerating) and they won't fade.

And as for cold rain and hot brakes causing your rotors to warp,I wouldn't know.It only rains twice a year here.And it's hot rain:)
