brakes are kinda like your body... if you want to give them a workout, you have to do a proper warm-up and cool down before and after. otherwise you risk warping and cracking the rotors. another bad thing is that people drive to the car wash and immediately hose down their wheels to clean them. you've got brakes that are a couple hundred degrees right behind those wheels, and hitting them with cold water causes them to crack and warp. not good. Slotted/drilled rotors are MORE prone to cracking and warping. drilled crack, and slotted warp. If you want the "best you can get for the money", then buy some brembo blanks for about $35-45 each and have them cryo treated for $15-25 each, and you shouldn't have to replace them again for years. : when i first got the car i did a complete brake job and had everything turned down but no more than a month later then needed it again. i do recalled doing one really hard brake then it was messed up afterwords. damnit its just a pain in the ass to do it all again. : are cross drilled and/or slotted rotors any more resistant to warping?
do some searching on brakes and you'll find that information all over the place.
I used to go through rotors every 4-5 months. I had my last set cryo treated and they've been on here about a year and are still going.
I've also got skyline rotors on mine and wilwood calipers, and the rotor surface has severe heat cracking, but it's only "surface" stuff. been like that for months, but the rotor itself is still solid. just hope it stays that way until I rplace them again.
