I will say though, that they stood up great against my first track day. They were very predictable and had no issues with heat. Since they stayed predictable, the soft sidewall wasn't a big deal since you get use to how it feels. Although it wasn't a hot day (around 65), so I don't know how they would hold up on a hotter Summer day on the track. I've read complaints that they get slick when they heat up quite a bit. However, none of this will matter unless you are tracking the car. If you aren't tracking it, they are very good substitutes for the stock tires and a ton cheaper.
