I've chucked warped rotors up in a lathe and checked them with a dial indicator. El-cheapo pepboys, etc, rotors warp way easier than good ones like brembos, stoptechs and the like.

If your rear rotors are warped it might be bacause you set the parking brake after going out on the track and coming back in when the brakes were super hot. The parking brake pressure on hot rotors forces them out of round and when they cool they hold their new shape. ie: don't use the parking brake at the track.

You can do as you wish..... , but if your outta money, getting them turned will get you back on the road for alot less money than buying new rotorz.

btw: I have a perfectly good set of used rear rotorz right now on ebay.

You can improve overheated brakes by taking some sand paper to the rotorz and pads to remove the glaze that occurs from the heat. It won't usually eliminate any pulsating but it will improve the grip of the pads. Obviously if you see any buildup on the rotorz, you can sand it all off.
