Deft is absolutely right. I am on my second set, and they are absolutely AWESOME at the track. To date, my best 60 foot with them is 1.799. However, on the street, they aren't all that great. When they are new, they are tolerable for all weather driving, even dry. They can be controlled in the wet, and do manage to bite some when warmed up on regular cement. Once they get smoothed out however, they are impossible in the wet. And I mean, ANY water. I've been caught in the rain twice with them, and it quickly turns into a 20mph trip, if that. You could sneeze at my car, and it would spin out of control. On average dry road conditions, they will spin on any sort of brisk launch. Once they have spun a few times, they will bite pretty good, but expect the gravel shower, because they have this tendency to coat themselves in pebbles once warm on the street, and throw them all over the side of the car. This is the second set that I've had, since thanksgiving last year. I've not even gotten 3k on this second set, and they are smooth as eggs. Now, don't get me wrong, I don't drive like an angel, and I do a TON of driving, so these are wearing quicker than average, whatever that is. IfI had the option, I would have another set of rear DD wheels to put a cheap Sumitomo on for regular driving, while these bad boys stick with track duty only.
