I used them to run the time in my sig. However, I went to the track this last fall on a nice 60* day to try & best my time.... no hope in Hell of them hooking with the extra power my car was making in cooler weather that day, along with the cooler track temps. I was so wishing I had sprung for 255/60's
They are a tad on the small side for a car that makes decent power.
