The SLK 230 rotors are 11.25" up front and the SLK 320 rotors are 11.8" up front. I was wrong on which setup the Limited uses.
I'd be real hesitant to mess with Derek on this. He's done his homework. This is a subject he takes seriously and is something that he relies on to keep himself safe every time he goes out.
The complete SLK 32 brake setup (f/r pads, calipers, rotors) retails around $2,600 but wholesalers can get it straight up $2,000. I have no idea what you can do the SRT setup for using local sources.


MMZ... all SLKs from 98 to 2004 are 170 chassis. That simply designates the platform. The Limited uses many of the SLK 320 parts and the SLK 32 relies mostly on the SLK 32 goodies. The only real are in the engine, drivetrain, suspension, brakes, and programming. The actual structure of the chassis should be the same. I know the SRT coupes have the convertible bracing under them and I assume the Limiteds use the same stuff.
My SRT definitely rides stiffer and has less body flex than the SLK 32s I have driven.
