I lined up against a stock GTR at the track and I have to agree that they're aren't all that fast on a roll. He roasted me off the line as I was nervous and asleep at the tree. Street tires and being a novice didn't help me either.
Anyway, once I woke up and stopped spinning, his lead didn't open up much more past half track. He ran 11.8 to my 12.5 (my worst of the day) but his trap was just 3 MPH better - 118 to 115. Tuned ones are a different story!
