I've ran them all on my S2000 as got a few sets of wheels, so had PS4, F1AS5 and Continental Sport 6, my favourite surprised me as I rate the Goodyear as best, traction hardly ever intervenes and the steering directness seems sharper, also great in wet. The PS4 are practically as good but I feel the Goodyears edge them in feedback and feel, the CSC6 are also fantastic, all three are super close but the CSC6 seem a touch less sporty and they also take a lot longer to bed in, all in all none are bad they are all superb tyres, but the Goodyear for me is my favourite on the S2000.
