I just got these today and they are brilliant perhaps the best mod i have done so far. I used the gtec tonight, my better times were 4.01 3.95 and a pb 3.90. I was in shock, its my first tire upgrade and have significantly improved my 0-60 which was 4.4 previously. A good rev launch sets me up to go full throttle right off the bat which was something i was never able to do in the past. Im going to hit the track soon and see what comes of this drastic improvement in gtec times
