My P1 came with the uprated prodrive brakes, so does that mean I can only buy pads from the dealer ??

depends, if the caliper says SUBARU, then you get those pads almost anywhere these days, but, if it says, PRODRIVE, then they'll be harder to find, not impossible, but difficult.

we supply a range of replacement pads from Pagid, Ferodo & Mintex for ALL subaru fitments..........the prodrive spec "Alcon 4pot" system is no problem
alyn - as performance

Demon tweeks as well

thanks guy's for the replies, I've discovered that the front brakes are the prodrive alcon 4 pots

cheers
