just reread this - didnt realise you was going on about JF2 - i was tired last night. RSR are a very good tyre, not as grippy as r888(not by much) however i believe they offer better value for money than the 888s. Im not going to be doing open pit lane at jf2, theres too many idiots out there for my liking, was a few close incidents last year, and with the open pit lane - mixed abilities on track, people will be out for longer than 20mins and not realise about tyres/fluids getting too hot - just accident waiting to happen.
