In Defense of J55 Brakes

The only thing that you might even consider an issue is on the rare cases there is enough pad dust accumulated that gets wet from say driving in the rain, it can run out onto the wheel and dry out. It requires some extra effort to remove from the wheel but a very minor issue.

I used the same and no issues with noise or vibration. Used C5 brakes up front and stock in rear. Was a pain clearing my FM5's. If I were to do it again would have stayed with stock J55's as only time I get on a track is during our C4 gathering at BG. Other than that normal daily driver.

Part of the reason the fronts stick out as far as they do is the brake rotor. With my stock Z06 wheels over the stock brake rotors, the tire would protrude past the front fender opening as u describe. With the Z06 rotor, the tire receded into the wheel well further, and then w the 2piece Coleman rotors and aluminum hat, its nearly flush.
I?m using an 18mm spacer for the stock rear Z06 wheels.

my issue is not the rotor but the c6 z06 caliper size. the caliper sticks out 2.22"/57mm from the hub mounting face. what i am looking for is a wheel that will clear the caliper and yet fit in the wheel well to give me a 57+/-mm offset.

with the engine out of the car right now, i guess it would be the perfect time/opportunity to replace the cams, but $$ seems to be in short supply at this present time and i never budgeted for them. between you, jerry's, marc haibeck, zfdoc, stainless works and jet hot, i managed to spend over 6k and my paypal shows it. i need to sell some more parts...lots of them!

Of course I did not have that issue given the use of the stock Z06 wheel.
