I stumbled on a set of '08 CLK55 6 piston front and 4 piston rear calipers in case you guys are interested. These are very hard to find, and the rotors are very inexpensive. I'd like $1,200 shipped. I'll post photos once they arrive.

Here's the link to photos and a write-up of when I installed a set on my SRT6. https://www.crossfireforum.org/forum...e-upgrade.html
