I’ve seen a few posts of people who have had their GLC 43 front brakes upgraded to the GLC63 brakes. What all needed to be swapped (besides the discs, calipers, and pads)? I’m only looking to do the fronts since the rears would be too much of a hassle because of the integrated ebrake. Mine is a 2016 fitted with 21” wheels so I’m sure they’ll fit.
