Does anyone know if w204 C63 brakes will fit on a 2015 GLK 350?

As awesome as that would be (and I think that any kit fitting the W204 cars is bound to fit ours - but take that under reserve...), I would think that you would need to upgrade the brake booster and/or master cylinder.

In my Legacy GT, I upgraded the brakes to STi brakes (Brembos 4-piston fronts and 2-piston rears) and without a master cylinder upgrade, they were worthless. Simply not enough oomph from the stock setup to push 12 pistons around (vs. 4 total originally).

Also check the wheel clearance depending on what you have for inside rim diameter and offset.

I think you can't go smaller than 19''.
