Rather impressed with the CSC7 having now done a few hundred miles on them in both wet and dry. Compared to PS4S on standing water at motorway speeds there is less steering wheel resistance driving over them which aligns with reviews saying aquaplane performance on the PS4S is better as the tread pattern disperses water better, but even it still feels confident in the wet when driving over those kind of surfaces, just minus the sudden steering jolt as you do so with PS4S.
The comfort on the motorway is also better than the PS4S when new, the sidewall is supposed to be stiffer than the PS4S yet feels more compliant at speed.
Grip seems just as excellent.
CSC7 tramlines though, and whilst I now have polybushes (purple+black series), I also found this to be the case when I had CSC6 for one round on the M3 years ago on OEM bushes so this seems to be a Continental thing. PS4S only tramlined on very specific roads whereas CSC7 does it most of the time. Not a huge issue as I'm not too bothered about that, if anything it keeps you more on the ball lol.
High speed stability appears to be just as good as PS4S, though I think the PS4S feels slightly more confident beyond 3 digits which is obviously not relevant for regular driving
I also like the slightly rounded sidewall shape vs the flatter looking PS4S sidewall design.
Considering the price vs PS4S, and as long as the tread wear life at least gets close to PS4S, these could be a repeat purchase for me next time round.
