Which model would be the stickiest one for the street?? Little rain driven, need much more traction...Will be using stock Z rear rims..

 

For what its worth I've run Nitto 305/35/18 drag radials for 2 years and they work great and have a reasonable life ~ 10K.

I've used the Nitto DR'S on my last 3 cars over 125,000 miles all trouble free. I know you asked about Kumho but I feel obligated to share my nitto experience/history with you.

 

Kumho drag radial? Is it new?

 

THe Kumho Ecsta Mx is the closet thing they have to a drag radial and it is only slightly better than the runcraps.They do not make their road race tire in Corvette sizes and according to a friend who had them on his 400 rwhp foxbody, they suck bigtime on the dragstrip.

 

Mickey Thompson is by far the stickiest DR out there.

 

Kuhmo makes an ECTSA V700 which is a R comp tire. Very sticky for the street, and do decent in the rain. I have been running 275 40 17 (they do not make a 265) for 13K miles and they are scuffed and have a ton left. I am on my 2nd set of 305 3018s, both on chrome repos and they are, IMO, too much tire for the street as they throw way too much crap on the car. I have run them a few times at the track, and they are not very good, and are a PIA to launch, but I did get a 1.83 60 on them after I had maybe 50 passes in the seat.

The ECSTA MX is a more street tire, and looks very close to the V700, but is not as soft and does not thrash the car as bad. A close friend has them on his car here, a DD, and loves them and he has went 12.0 with a 1.8s all day here. IMO the MX is a much better street tire. Hope this helps.

PS I like Kuhmos and if the MXs where stocked in bigger sizes, I would buy them again.

 

Kumho has a drag radial now ? Is there a link I can see ?

 

The ECTSA V700 is a road race tire, therefore it wouldn't be your best choice for the strip(very stiff sidewalls). BTW, KUMHO does not make any type of drag radial. Try Nitto, Mickey Thompson, or BFG.

 

I love my MX's for the money.

Very sticky at 400rwhp and when they warm up at the road course are a really good tire. Good life for the work I put them through too.

 

I run the ECSTA MX also and they hold of fairly well. As stated earlier ini the thread, they are not DR's.
