Ok I know the rear has the standard rear calipers, either single piston of twin piston. Do you think that upgrading to a 4 pot rear would be a bigger advantage than the. 6 pot fronts? I'm already running castrol Srf brake fluid and I'm looking into braided lines. I have been told by numerous ppl that there isn't that much difference between the 6 and 4 pots mainly because the pads are the same size anyway. So for me I think adding 4 pot rear, braided lines , some half decent rotors and good pads will work out unless I'm told otherwise
