Rory, can the Cup 2’s handle sudden downpours? How quick do they warm up in road use?
For a GTD I’d recommend Pilot Sport 4 (or the successor PS5) or 4S. Superb allrounders and the 4 (5?) likely to be slightly more comfy. I’m talking general all purpose road use here, not trying to shave hundredths of a second off in controlled conditions.
I’ve had PS4S’s on two Clubsports now. I was so impressed with them on my Ed40 that I immediately fitted them to my mk8 CS. In the interim I had a TCR with Pirellis (meh tyres) and a BMW 1er with Bridgestones (made of stone too I think).
Absolutely no hesitation in recommending PS4 or PS5 (tyres not gaming consoles) for their slightly toned down therefore likely better all rounder design brief if ride comfort was high on the agenda.
Fair questions, and just realised this is for a GTD.
Rain, when its wet I'm not going to drive like I stole it or may not be driving at all!
Ref the temps, hard question, obviously being a track biased tyre they will take longer to get to ideal temp and stay there.
So, maybe the PS4 or PS4S maybe the best option
I have tried the PS4S, they are also very good tyres!
