I stopped down at my teacher/mentor's shop yesterday to discuss my disc issues yesterday and he brought up an important point: ventilated rotors aren't always a good thing. Pad material depends on a certain temperature to function it's best. In competition, pads/rotors can overheat, glaze the pads, and experience fade. In a street application, in a ~1500lb car, that's nearly impossible. What vented rotors do in that situation is never reach operating temperature, hence never function to their highest potential. 

Yeah, I respectfully disagree. I DID experience fade on solid discs(CSP) on my old Spyder at about 85 into a 30 mph corner. Butt pucker for sure. That was after a series of many sharp corners/straights. On public roads. Not only is it possible, but if you drive hard enough, inevitable. 

At the time I had rear drums along with the CSP discs. Since the rear is what, 20 or 25%? It's not the lion's share, anyway. I had ZERO brakes, and with a dual circuit master, split front-rear. I really thought I had good brakes. I was wrong.

The drilled rotors make the difference, I've never experienced fade with the Airkewld brakes on all 4. On the track. On the street.

Back to the real subject, glad you got the imbalances taken care of.
