Hi guys,
Just a quick update on this, I've sold my current PZeros on the car to a neighbour of mine (for a good price who also has a GTI :-) ) so....... I'm just going replace all four tyres with new PS4S.
I hope they are a step up from the Pirellis. I did find them a bit lacking in the damp conditions.
Thanks for all the advice, much appreciated.
