Generally if you're running a race thats long enough to kill a set of pads it seems like you'll get 2 sets of pads to a set of rotors and you just throw them in the calipers and roll. I know a lot of people say to turn the rotors to get rid of the previously bedded brake pad material but what if you're going to run the same pad... in my case just running OEM for the brembos. I know its fairly cheap and honestly if im pulling the rotor i'd rather just replace it with another new one.

I know some people run different pads during a track day and then just swap pads when they go back to daily status with their car too... so i'm somewhat confused. Right now if i dont see gouging or excessive wear im just going to drop another set of pads on those rotors and let it ride...

does anyone have a real reason to not do this?

I always change the rotors. The rotors are cheap enough where you can replace them every time you need pads. The cost to turn rotors and the cost for new ones are near exactly the same price now a days so I'd rather not take the chance of having the rotor warped in any way.

its 65 a hit for oem rotors... turning them is 10 bucks a piece.

If your pad's the same, you can probably make the call to not turn or replace them as long as they aren't worn in some strange way.

I would not turn rotors at all, though. Stopping capability is not optional. Modern rotors don't have a lot of extra metal on them. Thinning them out is asking for trouble down the road. Replacements are not that much.

I don't turn them. Besides, the only type of grind that should go on rotors is blanchard grind, not typical lathe. I run Cobalt XR1 for track days, and then slap my stock Ferodo HP1000 on right after. Haven't had any issues, and the rotors are in great shape.

glad im not the crazy on thinking turning rotors have gone bye bye. I remember when I was in college, they pretty much said that these are the new door stops unless you deal with heavy equipment or full size/semi trucks. Cost<safety all day long in my opinion.
