I had a set of the Conti Sport Contact 7 fitted to my BMW M2 last year to replace its stock Michelin Pilot Super Sports, ran them on a couple of track days and some mixed road use until I sold the car. They were a pretty big improvement, the front tyres in particular felt a lot stronger than the old Michelins, less understeer and better balance. Response and steering feel was about equal to the PSS, but both are better than the MP4S which have a softer sidewall design so can feel a bit woolly (but are more comfortable).
Wet weather grip is seriously good compared to the PSS, which are a liability when it gets damp. The Contis are so good they almost feel like an all season tyre in the wet.
Wear seemed about in line with the PSS, at least on a full track day they'd both lose about the same amount of tread, can't really comment on day to day use though as I only did about 1000 road miles on them.
The Conti 7 is definitely what I'll be putting on my RCF when the time comes, unless the MP5S is available by then (they're 21 inch only at the moment).
