I invested in some Toyo R888's for todays track day and the difference was unbelievable.The first track day was dry with good quality road tyres and today was very wet.My lap times today were quicker in the wet with the Toyo's than they were in the dry with road tyres.The difference in grip is unreal.I even kept the Hyabusa Seven replicas at bay on the bends.If your going on track its well worth investing in proper track tyres.Only two minor spin offs in pouring rain so im well pleased.
