Being a total car nut, ie: It Can Always Be Better!.. I have a few questions about Benze parts. I was looking to upgrade the brakes on a SLK 230. Are calipers, rotors interchangable with say an S500? I've been researching thru what is available and it aint much. Short of going to a salvage yard and pulling the parts to see if they can be installed I'm not finding to much info out there. The other alternatives are those crazy priced brake upgrades that I'd probably never even need half the performance. Any help with this would be great.
