at the end for the differences.
My pad currently on my car is ME20 RCP 132. 58mm wide backing plate. See here
. I have the N caliper that takes wider pads by about 5mm.
I also can use RCP132 with my calipers.
The GTS rotors are restricting which are 51mm, that s why I had shaved Off the RCP132 to 51mm. Regular pad for GTS and Euro spec brembo is RCP124.
The calipers are never restricting, only the rotors.
That is the reason why I also have custom bells now for the Race rotors.
