Congrats on the new car :thumb:
My Turbo S was on Cup 2 tyres when I bought them, and TBH the only time I noted anything of concern with them was that the car was slightly twitchy when it was cold and very wet in early January.
Otherwise the car rides fine on them, in comparison to the PS2's that had been on my previous Turbo, and the grip in dry conditions is phenomenal. I would stick with them if you intend to avoid crap weather, and reconsider when it comes time to change.
