The ECSTA V700 is the newest competition tire member of the Kumho ECSTA high performance tire family. It’s a DOT legal competition radial that was developed in Europe and is now available in the United States for the drivers who participate in autocross and track events. Like its companion (the Kumho V700 Victoracer) the ECSTA V700 is attractively priced and designed to be a great "racing value" by delivering the best traction and treadlife per dollar.

The ECSTA V700 molds Kumho’s specially formulated high grip Silica competition tread compound into a directional design that features wide tread ribs in the shoulders and intermediate tread blocks to maximize dry cornering grip while enhancing handling and tread life. The ECSTA V700’s directional tread design also helps provide wet traction when run at full tread depth, however, if there is a lot of standing water on the track, caution is advised and/or the use of deeper treaded tires is recommended.

The ECSTA V700 is molded with 6/32" of tread depth in its two major circumferential grooves and is available unshaved (for autocross competition and road racing on damp tracks) and shaved (to between 3/32” to 4/32" of tread depth for dry track use).

The ECSTA V700 has two steel belts reinforced by two nylon cap plies to help stabilize the tread area and provide high speed capability. Additionally, a symmetric internal construction featuring three plies in the sidewall enhances quick steering response and high speed stability. As the tire's outer shoulder tread wears from hard cornering, the ECSTA V700’s directional tread design and symmetric internal construction allows worn tires to be remounted "inside-out" on their wheels to prolong their life.

 

I believe they became available in early October. I just received mine today.

 

Well... I saw them back in July, but that was a "prerelease" for a privileged few (and no, they weren't my tires, they were 18" tires for a friend's Z06). I think Chris is right about the approximate October date most sizes became available. Tim Aro and Rod McGeorge were playing with them at the November autocross, definitely.

well...i guess i won't ask if anyone has used them yet in an auto-x. They look promising though.

 

I'm running them in 225-45 15 up front right now... have used them at 2 autox's but have yet to really break them in. They feel like their sidewall is stiffer than the Victoracer's but ultimate grip feels a little down right now. From talking to someone else who has them it appears that they take more track time to break in than the Victoracer's did. I'm going to be using them at Roebling road at the end of Jan and I should have some feedback after that... hit me up on IM if you want more info after 1-26/27

 

I autocrossed on them once. Can't say if they are better/same than the "old" Kumhos, but I don't think they are worse. Predictable like the other Kumhos; seem to need a bit more pressure; sidewalls seem a bit stiffer; some different sizes than in the past, like 225/50/14.

 

I'm thinking about getting the 215/50-13 for Solo 1 next year. Hell, they're only $95 per tire vs $129 for AO32R.

 

I've had a set of these since October, I've ran 1 auto-x and 1 track day at Sebring on them. I got them full-tread and they have a stiffer sidewall than the Victo's and by the end of the track day the grip seemed to be equal but easier to control. They are the same 50 treadwear rating but seem to take longer to break in than the Victo's were.

I dont have the tires personally but rode with B18CJDM at Sebring and was amazed at the amount of noise they made vs. the old victos. It makes it a great way for a "beginner" to get used to race tires. They let you know whats up....
