I've got one track event on a set of slotted Alcon front rotors with
Carbotechs all around, and so far so good. Stopping power during the winter
has been fine, they don't seem to require any more pedal pressure, although
they do squeal like pigs...
I warped three of sets of stock rotors in less than two years - one at my
first track event in the car, the second to a Chicago winter, and then the
third at another track event. I figured I was pushing my luck going back
to the dealer again two weeks after the last replacement - and seeing how it
was my fault anyway...
Working with the guys at MotoPersona here in the Chicago area, we bought the
Alcons through Stasis Engineering (~$900). The big benefit to these is that
they fit with the standard calipers.
So far they've worked great on the track - I was getting a bit of brake fade
on the last run of the weekend at Gingerman last fall, so probably time to
upgrade the fluid. I'm planning on doing 2-3 more events in 2003, so we'll
see how they hold out.
All in all though, a fairly reasonable solution to the dreaded brake warping
problem - the dealer quoted ~$900 for replacing the stock rotors, so not
much more $$$.
