What are Stoptech's? How are Hawk Blue pads are tough on wheels? Is the brake dust somehow worse than other pads for the finish on your wheels? I'm running stock wheels, should I cover them in blue tape for track day? Or can I just clean the dust off them with a microfiber cloth after each track session? I do have a set of track wheels but no rubber for them yet and I have already spent too much on my Z YTD.
