I’m with you! My GTR, and my R8 had steel brakes and it was hell! Especially the R8! One short drive and they are already dirty! Now life is good with the CCB’s on the SL. I even ceramic coated the calipers and wheels to make it even easier!Having had steel brakes before I can really appreciate the CCBs. The cleaning used to be a nightmare and now it's absolutely nothing. Not to mention the brakes are fabulous.
