I've done a few autocross days on these tires on my K24 EG hatch. The handling is very precise but the straight line speed is a little bit behind more expensive competitors. The tread life is very good and you should be able to get a full season out of these no problem. They also don't like being cold and need a few laps to start working good. On my EG the car is very oversteer prone with these tires, possibly because it can't ever get enough heat into them. On a hot summer day in Texas they probably do excellent.

I have these on my 2011 135i, around 600whp, fully upgraded suspension include spherical bearings everywhere. They warm up quickly have excellent grip going straight and while cornering. So I can use them for both half mile racing and hpde. Compared to my last set of tires, federal fz201m, these have much more grip and are dead on the freeway. I have completed one track day starting with 28psi cold, and the wear was even and very good. Thanks kumho and simple tire!

Aren't that bad in the rain as long as you're going 5mph under the speed limit lol

If you want an all out street legal race tire for the dry this is it. These tires grip like a road racing slick. There performance is unreal. Everytime I throw them into a corner I am amazed at the level of grip. A few times I have been caught in some heavy rain and I was nervous but they did much better then expected. If you want a tire that grips like snot on a wall then buy them. I will buy another set when these die!

This Kumho Ecsta V730 are an amazing summer tires, excellent grip on thigh turns at high speed, very low noise & the look of the contact patch and sidewall is pleasant to the eye

One of the better tires available for 200tw tracking. Slightly slower than RT660, but will last a lot longer during a session. This tire also seems to get faster as it wears as well, as the outer tread disappears into a slick.

When I could no longer find RE71R's I switched to the A052's and when they ran out I switched to the V730's since the RE71RS kept getting delayed. This is my 2nd set of the V730's and I am reasonably happy with them. As sticky as the A052's but don't quite last as long. Both of them were better than the RE71R's. I did have one of my first set start to delaminate but the tire was worn and I think I was not on top of the temperature as I should have been. I will stick with these for now.

I used two sets of these for Track Cross days at Summit Point on two very different cars. These Kumho V730's are fantastic. I put a set of 205/55-16 on a Mercedes 91 300TE 4matic a while back and it had more grip than power. Great on the track. Very composed on this AWD wagon. I then put a set 235/45-17 on a 2006 Saab 9-3 Aero and took it to a track weekend. These tires really worked great. It was cold in the morning (35-40 degrees) and the tires took a while to heat up. They were squirmy when cold, with the tail coming around on aggressive corners. Easy to control and no bad habits. They broke away predictably. They don't like being cold. They were much better in the afternoon on the first day with temps in the 50's. On the second day, temps were in the mid 60's and these things stuck like glue. I think they are pretty tough and have even wear and will last quite a few sessions at the track. I drive about 100 miles to the track and they are fine on the street as well. Good ride and not loud. Overall, a fantastic 200TW tire at a good price.

This tire is absolutely amazing, I have these on my 97 Miata and the grip is unbelievable. Even it being a 200tw tire they are still lasting quite a while even with 4000 miles of hard driving on them.
