1500 miles up now. The Vredestein Sprint Classics, took a while to settle. Their grip is not quite up to the Avon standard, but pretty good. I have to try quite hard to get them to lock up under braking. Emergency stops need care. Lateral grip is good. Have not found the limit, need a track day to find that.
Grip in heavy rain is good & so far no sign of aquaplaning.
Despite being the same size as the Avons their diameter must be slightly less as getting more ground contacts. Thank goodness for Cain’s rubbing plate.
