2004 E500 4matic - caliper swap?
After long searches, I'm not finding much. I have 2004 E500 4matic, uses 330x32 front rotors. I have no issues with stopping abilities of this car, but these factory 2 piston calipers are ugly as sin. All I'm seeing are factory Brembo calipers made for 312mm rotors at the local yards and ebay. I know larger AMG brakes can be fitted, but I don't want to re-drill or modify the spindle or the carrier brackets.
Are there any factory Brembo (or similar) calipers from other W211 (or other bodied MB cars) that would bolt up directly to my car (similar to R129/W124 route for "Silver Arrow" direct swap conversion)? Even if I need to change the rotors (as long as I'm not going down in size)?
Thanks for any feedback!

RWD hat height 64.9mm (07-09 E550)
4matic hat height 47.7mm
They did that to make room for the front CV joint. That made the gap between the center line of the rotor and the wheel too small for fixed 4 or 8 piston calipers, the type you see in RWD E500/E550/E55. Your only option is the "ugly sliding calipers you have now where the 2 piston have to be inboard of the rotor.
RWD W211 brakes on the other hand are all interchangable. I replaced my E320 295mm single piston front brakes with E550 330mm 4 piston front brakes.

I will suck it up, will paint them some darker graphite color and will hope to find a yet another set of Carlsson 1/6 in the future... Thanks again for your time!

P.S. Nice looking setup! Stoptech rotors (or something else)?
You might be able to use the same RWD E550 caliper on your 4matic if you added a wheel spacer. The rotor diameter and thickness is the same the only issue is clearance between the caliper and wheel spokes. I guess it also depends on the wheels you have. With the standard MB 17" 5 spoke wheel and RWD there's a ton of room between the caliper and wheel.

I would gladly share if I do find anything to match on these 4matics...
I'm currently in the process of refinishing standard 1/6 (18x8.5 and 18x10) for my SL500, epoxy coated, color next... It took me 5 years to find this set!

these are a rough fitment of my 2002 cl500 4piston brembos on my 2005 4matic wagon e500. The 330mm rotor from the e500 is actually too large in diameter for the cl500 calipers, despite the cl500 also apparently having 330mm diameter rotors. This makes me wonder if a 315 or 320mm 5x112 rotor may work very nicely. I was able to get the caliper bolts to start threading, but not fully threaded in while mounted over the e500 rotors(calipers wouldn’t clear the rotors fully). Perhaps grinding away some material from the calipers would work if a readily manufactured rotor isn’t already available
In regards to hat height, I think some washers as spacers may have been enough to split the difference. Once the proper amount of offset needed with washers is determined, a sturdier setup can be setup with a metal plate
the cl500 these brembos came off of, was also easily upgraded to the amg w216/221 390mm front rotor kit by drilling out the spindle knuckles to accept 14mm bolts instead of 12mm bolts found on non amg brakes of the era. IE huge 390mm brakes could seemingly be fitted to even the 4matic cars possibly with little fabrication involved (minor cutting and grinding)
someone mentioned the wheel spokes would have difficulty clearing the caliper, using wheel spacers and being mindful of the wheel design could solve this issue
