Yes the e63 uses the same pad as gtr but thicker so if we used a 32mm width disc we can use r35 pads.. my question is then though will we be more prone to cracking discs? Apparently not if we used j hook or grooved I'm being told
If Luke doesnt take these i'll have them as a spare set.
But regarding moving down to a 32mm thick disc, thats quite thin in terms of heat management, i mean its a heavy car, it already has (in my opinion the too small wheels and small brakes)
RS6 come with 380mm out the box and 420mm Ceramics, i ran 410mm AP Racing Steels on my C6.
I'll be looking to move upto a 20" wheel soon, maybe some vossens i dont know, lot of money just for wheels really.
But yeah then some nice big 410mm brakes to finish off the Benz!
