Of course, the W124 and R129 4-pots aren't as pretty, nor as big as the C32 brakes, but they are more than adequate in terms of stopping power.

I took the Brembo 4-pots off of one of our 500Es and put them onto my 16v. After a season of autocrossing on them I don't believe there's any need for me to go any larger.
