Brakes upgrade

Did anyone installed W220 front calipers on W203? W220 I have are 330mm four pot

I've seen it done on SLK r170 forum is the mounting on R170 same as the w203?

The issue is the offset or height of the rotor hat. W203 and w209 4 pot calipers will all fit. I used w211 E500 4pots on my w203 because they were smaller (312mm) thinking so they would fit inside 16" wheels. Turns out it was a waste of time because 330mm brakes fit just fine. I had to make some modifications to the e500 calipers to make them fit. Again the offset is important. If I had to do it again I would use CLK 4pots.

Great I wasn't sure if the W203 has the same mounting as R170 or R171

Was busy with work. Found 330mm discs and guy had 4pots that came off W203 so I bought them. I'm gonna sell W220 calipers.

I took some measurements and can confirm that 6mm spacer will be needed to install W220 calipers(as long as they say "330" on the side) on W203. W220 are easier to find as cars are cheap. Calipers do look the same except the mounting ears. Didn't compare piston sizes.

This mod will work with W203 330mm disk. Don't have W220 disk on hand but offset is not the same as W203 one.

Left W220, Right W203.
