Have run a set of cp5200's 4 pots and 330mm discs on my RWD sgt 3 sapphire, a lot of my mates run similar set ups, and I don't think anyone has ever had anything apart from 110% performance out of them Mine get hammered every time I drive the car, and have had no probs at all. Pad choice is as ever, critcal though, the green stuff pads they came with were utter wank , a set of frodo ds pads made them much better.
