I've put the info in the comments on one of the fb group discussions and decided to put it here for everyone else.
This is a 13" BBK that is completely bolt on with no modifications except for cutting of the heat shield.
What is needed:
-Mercedes benz 220 s-class 4 piston calipers. Something like a 00 or 01 model s430/s500.
-Here is a link to a current auction.
-2012 Mercedes Benz R-class rotors. There 330mm tall and 32mm thick.
-They can be purchased on rock auto drill and slotted for like 70$ each(something like that Dont know exact numbers) or blank for cheaper. Also available at any other auto parts store as well.
-Yes the bolt pattern is 5x112. The R-class, GL-class, and ML-class all use bigger wheel bolts which allow the rotors to slide on no problem.
Hub centric rings:
- You will need 60mm ID to 67mm OD hub centric rings.
- Reason the rotors will not be centered. Use the rings and then the rotors will be centered thus preventing any alignment issues.
- Mercedes Benz 220 caliper bolts.
- They are different threads than the mk3 calipers.
- 4-5mm of washers
- Reason is the caliper needs to be spaced out slightly to be centered on the rotors.
-----The calipers use the same exact bolt spacing as our cars. With the rotors mounted the calipers need to be spaced out a little bit to line up with the rotor perfectly.
-----The stock brake lines and banjo bolts are bolt on as well. I would recommend getting new crush washers and preferably thicker ones as the bolt can bottom out inside the caliper which would prevent it from sealing.
-----The stock backing plate/dust shield will need to be trimmed off or bent out of the way by a good amount as the larger rotors sit father back and are taller.
-----Also be aware that these calipers will not fit on every wheel. They need a higher offset wheel or something with concave disc like a te37 or something like that. My xxr521 +25 18/10 would not fit with these calipers.
-----Thats about it. Everything bolts on like when doing a standard brake job.
