All depends on how you drive it mate!
Ive had firestones on all 3 of my cars, and they last very well if you drive sensibly.
If you drive hard on the other hand, they dont tend to do so well. i think there dry handling and braking is pretty good, but in the wet they tend to understeer alot!
Ive been reading a few reviews on various websites, and im probably goin to go for yokohamo parada 2s next, as they are said to have a harder compound and quite good wet grip.
Im sure there will be a few others along to cast there opinions soon!
Also join up as a FULL member and you may be able to get discounts from a few suppliers, its only £16 a year, and you will easily save that money, and more!
cheers
