Well, i thought i better drag this thread up again to give my opinion of the CS3's now that they are fully worn in.
They are fantastic.
I never thought i would be saying this and at one point i called Continental because i was afraid that i had counterfeit tyres and i was looking to try and return them and get something else put on the car - but boy am i glad i didn't.
About a week after i posted my original thread i started noticing how much they had improved. This was when they had had about 750 miles put on them. The amount of grip they give is simply staggering and nothing seems to catch them out. If you haven't turned in enough going into a bend, you can just tighten your line with no drama and not worry about the car throwing a hissy fit (which the RE050A's used to do) - i think this is mostly down to the slightly softer sidewalls, but it makes the tyre so much useable on the average road. Even in the soaking wet they just don't seem to ever lose grip. All that stuff about the traction control light coming on when i accelerated hard in second, and the ABS kicking in way to early has disappeared, which leads me to think that at 500 miles, the tyres still weren't fully worn in.
And i also thought my opinion of the turn in, compared to the RE050A's, wouldn't change either, but i don't know if i'm just getting used to it or if this has improved too? Either way, i don't care, because, and i say this with a touch of caution, the car feels better than it ever has before. There is none of that fidgtyness, crashiness or bump steer you get with the RE050A's, but there is still all the grip there.
Given the option, i would definitely buy these tyres again as they have turned the car into what i imagine it felt like the day it rolled out of the showroom.
For anyone reading this who has recently bought Conti SC 3's and hasn't found them great - give it time. Also, check, double check and triple check tyre pressures.
