Brembo makes the rotors for probably half of the auto manufacturers out there, and they definitely make good stuff. And they're cheaper than OEM. Dat why we buy them.

Also, there's very little performance gain to be had with the slotted/dimpled rotors for street applications. You pay a penalty in pad wear and noise (brakes make a whooshing sound when braking hard)... so as cool as they look (and I admit it - they look very cool), standard "blank" rotors are plenty good. Don't skimp on the pads though. A low temp compound Hawk or EBC pad will make a huge difference in stopping power and moderation.
