Others can talk, Carbotech performance speaks for itself. Carbotech brake pads continue to be the hottest combo going right now at the front end of the field.
We prefer the XP10 in the front and the XP8 in the rear. We almost always put a less aggressive pad in the rear for brake bias reasons. It really gives the car a very nice balance, and as a result the driver has more control of their race car.
Brakes are a very personal preference item, so we'll leave it up to you to decide what you think, and then let us know. It's a small price compared to other things everyone is doing to pick up that kind of speed.
Price per pair.
