Would anyone who has tried these give us feedback? Thank you!

Arthur, just saw your post. Used them (actually a bunch of us used them) @ Road america over Labor Days' 4-day event.
Although I also had to get new front rotors (Frozen) they seemed as good as Pagid Oranges. I'd use them again.

Hey, no probelm. Just wondered if the rotors being slotted are that much better than cross drilled ones, and if they are better than Brembo. Cheers

 

Arthur,

Briefly, there are two types of "cross drilled" rotors, those that are actually drilled, and those that are made with cast-in holes during the manufacturing process. The true drilled rotors should be avoided, as they will crack hole-to-hole fairly quickly, especially at the track. Rotors with cast-in holes, like those used by Porsche and also available through aftermarket channels, last much longer, however, they too eventually crack hole-to-hole. (For cast-in hole rotors, I have them cryogenically frozen). Slotted rotors have alot going for them, as the slots help to relieve gases and water from the brake pad face and rotor, you have the inherant heat sink capability of the rotor intact, and you don't worry about cracking between holes.

 

Thank you, Greg.

 

Cracking Never heard of it...
