my mate had some on his m3 evo rears and reckoned they weren't to clever in the wet when they were knackered he replaced them with some hancook ultima sports which were a lot cheaper and he reckons are 10 mtimes better in all conditions.
He has just fitted 4 to his P1 as he reckons they are better than a lot of more expensive tyres.
I reckon Goodyear F1's are awsome but they don't last very long.
