KUMHO ECSTA V700s on the rears!
My 60' dropped from a 1.89 on Pilots to a 1.68 on Kumhos at the track.
My 1/8 dropped from 8.0 to 7.5 and my 1/4 dropped from 12.3 to 11.6.
On the street if I cruise at 3500-4000rpms in 1st waiting to race someone, I can nail it and dead hook. With the Pilots I would be off the road somewhere.
For safety, Kumhos are the way to go, with Pilots your life is at risk.
I have raced solid low 11 second cars and high 10 second cars from a roll and the Kumhos allow you to STICK (no pun intended) right with them.
As far as I am concerned there is no better street or strip tire.
As a comparison -
My Viper cut a 1.68 60' on Kumhos and my 470rwhp Stang cut a 1.66 60' on BFG DRs on the same day at the track. On the way there I was able to hang with my Stang (my buddy was driving it) from a roll as I hooked while he spun.
Hope this helps,
Howard
