How about this... I have the Powerstops front and rear, cross-drilled, with stainless steel lines. They work great, the pedal feels better, I can control the amount of stop better, but I don't take my car to the track. The Powerstops that I received state in the instructions that the rotors are NOT designed for track use. I haven't warped these, unlike my stock units. The guy that installed the Baer's has been on the track, and plans to go again. The Baer rotors he ordered are slotted, and are vented (they all come vented, but are not of a two-piece design). He paid about 825, I paid less than 500 and some change for my set-up. I'm happy with mine, he's totally stoked with his. But, if I had the money, I'd have Baer's also. It's not a waste of money if it's not YOUR money.
