I went for the F1's a while back mate, mostly because they were about seventy quid cheaper for a set at the time. Think you'd struggle to get a fag paper's worth of difference between them on the road tbh. Very happy with the F1 though. Had the winters on the past few months, be nice to get the F1's back on this weekend though, the winters are ok, but the F1's grip is phenomenal.
“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”
