Got all my yokohamas on the wheels today, ready to fit on to determine the overall track width for the rear, I am hoping I can use my 4x4 callipers for now but will go to something like a 4pot from modern car or AP all round eventually, it stops well but I would like the modern stuff if I can.

Are AP's lighter than the standard stuff being ally or are they just the same as larger and bigger pads?
