Contour Enthusiasts Group Archives Forums Modifications Brakes Gas slotting vs. cross-drilling...ALSO Brembo/Eurorotors

I just recieved my Powerslot rotors from carparts.com today ($125 each + ship). I debated long and hard about what type to buy and decided to get these for 2 reasons. First, Powerslot is said to use Brembo blanks. Many different sources told me this. Second, testimonials from Corvette, BMW, Camaro, and Mustang guys on various chat sites about auto crossing that rate these highly.
I also read an article in a racing mag that said cross drilled rotors are prone to cracking and do not have an additional cooling effect. The drilling is for weight reduction and on small rotors may actually decrease their abillity to soak up heat. Slotted rotors actually do swipe the face of the pad clean and are not prone to cracking since the slots are not right through the rotor. Hope this helps.
