Like moppie said, it may not increase (dramatically or whatsoever) braking performance, but you guys seem to speak of it like it's the antichrist.
If it's as useless as all of you say, it wouldn't be used so much. It may not be useful in all respects, but it's certainly better than solid rotors.

That's the thing, if it's MORE prone (at least twice as prone) to warp or crack than solid rotors, it's not better. Braking force/performance aside, I'd rather have a reliable rotor (solid) that may not brake as well, then an X-drilled that'll mose certainly crack way prematurely with the kind of driving I do. You will not see x-drilled on professional race cars, and it has nothing to do with bans on them, it's all the principle of the matter which is those kind of rotors (x-drilled) on severe duty cars is dangerous. And the cars they ARE used on, again I assure you as will almost anyone else on here, that x-drilled rotors on Ferraris, Porsches and the like are sadly for looks, and nothing performance wise.
