Ive got redsfuff all round, this is my 2nd set. They ARE a good pad, with a massive improvement over standard. Granted the Ferodo DS2500 are a bit better but Redstuff are more than capable.
As theyare a ceramic pad they take a while when you 1st drive the car to get some heat in them, so they wont work 'as good' for the 1st part of any journey (depending how much braking is being done) but once you get on some back roads they are brilliant.
DO NOT buy the Greenstuff, they have a no more than 200bhp rating, and as the standard CTR is just shy on 200bhp it means they are always on there highest limit and a few sets have 'burnt out'.
