My set has been very disappointing. I assumed that for nearly $2K the rotors would be zinc washed and were NOT. I got the brakes mostly for looks within my 18" 5-spoke, very open SSR rims. What I got is a rusty ugly rotor that looks no better than the $180 Brembo "el cheapo" rotors I have in the rear, which ARE zinc washed. And the worst part of this brake experience is that they do not stop appreciably any better than the stockers and vibrate like a paint mixer when the brakes are applied.
Please no loose suspension commens, stock system worked w/o flaws.
