If you burnt the surface maybe you can turn them the other way and use them again.
there are brake pads on both sides.
have you done the brake mod, where you use fuel line instead of the spring? do that. and 270 aint nothin. mine were over 400 at one point, and they are still fine. if you havent done the brake mod i suggest you do it, and when you go for new disc get a steel one off of ebay
