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.
