i had some F1's and they scrubbed out really fast in my opinion, dont get me wrong they stuck like glue but i couldnt justify getting through tyres that quick.
It was recommended to me to get bridgestones they were about 99 quid each and i can only praise them i have been known to give the car a little stick so to speak and they do perform, but the bonus is i had the car up on the four point lift yesterday to change the oil and they are wearing really really well and evenly!!
