my kumho MX were pritty sticky but those things wore down quick...

 

For ultimate street tire dry traction without regards for longevity and with out using a true R comp, I'd go with Azenis sports. Keep in mind though they will get greasy if you autox in hot weather, and they will SUCK in the rain, and they will NOT last you 25k miles.

 

under heavy race conditions the new 615 tire didnt get greasy...and it has MUCH BETTER wet traction compared to the 215's.....plus if you are leaning towards the 215 tire you better get them quick once the available product is sold out they are gone forever.
