i have used dunlop 207rr
bridgestone bt014s and 12s
all work very well and get good milage but it all depends how you use them.
done lots of road miles and a couple of trackdays and all fine
use rennsports at the moment very sticky but not to many miles on them.
dunlops cost me £150
bridgestones£160
and rennsports was free as i was given them.
