I have a trackday end of June and I have replaced my aged Conti M3s on the front with a set of Michelin Pilot Super Sports. Now on the rear I currently have a 5mm tread set of Goodyear Eagle F1 Asyms 2s. I am just thining about how the balance and grip at the back will be with the soft fronts biting at turn in, I wonder if I will end up with a day full of oversteer with the rear being unable to compete. So do I leave the rears as they are, swap to PSS or something else? I am running the stock 18" wheels and standard tyre sizes.
