Based in the increase in rear bias w/332's, I'd suggest you always run a more aggressive front pad.

Default Excellent Info. Interesting how the S8 rotors seem to have less of a vent gap...

than the stock ones.

Default Maybe better cooling. Keep in mind they're doing more work now which means more heat is generated...

...back there, so cooling has to be better just to keep up. Of course, that means the front brakes are doing less work and they can cool off better.

Default no brake tests yet, I haven't bedded them in.

I don't expect to notice a difference in braking performance, though. I needed new rotors, and S8 rotors were an incrementally more expensive option (money-wise ). Also, the S8 rotors are better are protecting the rear bearings from heat (seems there are a lot of rear bearing failures lately). Besides, it's fun .

I think a slightly higher rearward bias might eventually make sense if I lower the car, but again, this upgrade's primary motivations didn't include better braking performance.

I'll post impressions after a week or so, if I have any.
