I don't know many people who've had a good experience with Tar-Ox stuff
Obviously Brembo, AP Racing and Alcon are the top dogs in that sector, but costly.
Yellow = A big fat hell no for a road car.
Red = Worth a punt if EBC have improved the compound in recent years as Breeze said, because otherwise, EBC are the worst pads I've ever experienced, ever ever ever!!!
DS2500 = Over rated meh. Good on paper but in practice, very underwhelming for the money. Very dusty as well, and not the 'nice' dust that wipes off easily, but the kind that burrows into wheel lacquer.
The MK7 R or S3 brakes are plenty good enough to be fair
I've used 4 pot kits in the past and the improvement never blew my skirt up to be honest, except when really standing on them from high speed with seriously sticky track pads.....but how often does that happen on the road?
I just couldn't live with the squealing, sqauwking, clicking, clacking, knocking and clunking...... and all the dust .....and the massive cost of replacement rotors (Yes you, AP Racing) blah blah. Stick to OEM brakes
