i'm getting the Dunlop Z1's installed this weekend. if i don't like them when they're done then i'll try the RE11's.
one of the guys at my local Discount Tire rally races a supercharged Miata. for street use, he says these are the top tires (he prefers the Dunlops).
the RE11's are about $50 ea more than the Dunlops.
i have one ~200° turn that i take every day and my RE760's just never felt right being pushed that hard.
