Bought these tyres because of the lack of wet grip and quick wear on my previous GoodYear Eagle F1 SuperSport, to which the new ones were driven straight back-to-back.
First off the bat, the SC7s are way quieter, way more comfortable, the small bumps and imperfections don't make as much noise as they did on the SSs. The steering feel was more direct - the SSs had a slightly longer delay in response to steering wheel inputs compared to the SC7s, the Contis still have a delay, but just a little shorter one. Dry grip was lacking on the SC7s, but that was at first thought to have been just due to the tyre being brand new and not being run-in yet. On the wet, I've taken it easy for the first thousand miles to not have an incident on the road.
After about 4000 miles, I can say that the SC7s are a straight dream in the wet. Where the SS would start to understeer on tight corners, the SC7 would show not even a hint of deviation from the wheels' direction. Where on the SSs the car would laterally slide out of the corner on hard acceleration, the SC7s would allow for as much acceleration after the apex as the puny 240HP allow the car to at a slight steering angle. So a complete dream to drive in the wet. Even after the tyres were definitely run-in, the SC7s would leave much to be desired in the dry. The dry grip is good, but the SSs edge the SC7s. Where SSs were driven hard with some safety reserve, the SC7s would already lose grip and slide, bringing the comfortable cornering speeds down significantly. Where on quick alternating turns and changes of input the SSs wouldn't even flinch, the SC7s start sliding and shift the car laterally. Pre corner lift from accelerator pedal to braking pedal while already turning in the corner would shift the entire car outwards. Mid corner change from acc to braking because of a bad corner length estimate does the same on the SC7s. The SSs didn't care for abrupt imput and transfers, they would just stick to the asphalt.
The conclusion on the tyres is still, that these SC7s are the best tyres in the wet so far, but for the improved wet performance, noise and comfort over the SSs, the sacrifice on dry performance was made. That leaves me somewhat disappointed, as the SSs were so bad in the wet they weren't really fun at such low corner forces, but the SC7s shine in that area. So the only current solution is to have a dry set of tyres for my car - Goodyear Eagle F1 SuperSport, and a set of wet tyres - Continental SportContact 7.
I really can not comment on the wear, because the both tyres are awful in that regard, but that's not a problem, as it's way better to be safe and glued to the asphalt for the 8000 miles I got from a set of 4 SSs with rotations and maybe 9000ish I expect to get from the SC7s, than to have tyres perform badly and last for 13000 miles or even more.
