I have just put a set of ZV7s on my Aero8 to try them on a different set of wheels to Michelin PS4 I have on my other wheels. I'm not a little concerned by IvorMog's comments as I'm going to the BHM trackway at Goodwood next week and was intending to run the ZV7 as they appear to be more dry rather grip focussed then the PS4 giving better all round performance, particularly in the wet.
Paul, you can read a comparison
here which confirms IvorMog's comments. However neither are track day tyres if you want the ultimate.
