Worthers, I have new Pirelli P Zero Neros on my S1 Aero, they are pretty grippy, but mine is tuned to 330bhp and I have noted as PeterK says that under hard acceleration in 2nd or 3rd especially at around 4500 rpm who the torque really starts to kick in the tyres can start to be pushed to their limit of adhesion even on a warm dry tarmac. This can be felt by a slight momentary loss on acceleration and then a sudden rush as grip is regained, not something you want going round a bend, also I would not to experience on side letting go and the other loosing traction, even in a straight line.
Have fun.
