Finally got the chance to try these out on track this morning. It was a wet day which was unfortunate. I can categorically state that these are the worst tyres I have ever used on track in the wet. I would have had more grip from plastic tyres!! The car understeered like I was driving on snow/ice and the rear end tried to overtake the front of the car at every opportunity. It was absolutely impossible to get any heat what so ever into the tyres. I played about with tyre pressures & driving styles all morning but to no avail. I eventually gave up trying to make any progress and spent the rest of the track day going sideways. The tyres work very well for this purpose.
I will give the tyres another chance on a dry day but I won't be expecting much from them.
