after you replace the fronts -- just use the OEM fronts which are HUGE and relocate to the rear. Surely some fab. will be needed but should be awesome when done.

We have silver 6piston 405mm with silver 4piston 380mm rears.
Brembo also makes a 8 piston 380mm front, and also a 4piston 345mm rear.
Also you can not move the front disk to the rears as the rears need the hat to be deeper for the E-brake.

You look at Stoptech, KSport or Rotora? Not sure of the quality, but you are not going to find much for less than $4k for front and rear bbk, unless you come across a used set of AMG units for a good price.

I can help you with this as welll... we have a set of used CLS63 brakes. I honestly dont know how much more of an improvement these will be tho... your issue is with the SBC.
