Yeah may try that tomorrow, just Rally Design said the wider M/C should drive the rears, something to do with hydraulic power/pressure calculations that bigger cylinders give LESS pedal travel and LESS power, smaller M/C's give MORE pedal travel but MORE power. I know that sounds backwards but that's what they say!
Won't do any harm to try though...
Using mintex ST170 front pads at the moment as I drive predominantly on our hectic roads so wanted some "instant bite" rather than fancy fast-road pads that need warming up!
