I know this is an old thread but I'm upgrading my 1999 C230 Kompressor to Bigger rotors and Calipers

What I am using:
2000-2 CL500/S430 Calipers ($100 ebay pair)
2002 SLK32AMG Rotors 330x32mm (amazon $36 each)

problems I encountered is I had to space the calipers 10mm and use 45mm long M10 caliper mounting bolts
this is due to the rotor offset. I found some GLK rotors that move the rotor back 8mm but have not found some to play with yet.

found some longer brake lines that would work from a 64 VW Bug 19" long (about 490mm) ($10 each)

Trying to find some used SLK32 backing plates ($200 pr NEW). Ordered some for a E430 4Matic ($40 pr NEW) but it uses the wrong mounting since its AWD.

Has anyone done the same conversion??

My 95 C36 I am going to go to E55 Brakes. Since the rims on that car is 18" already
