I said I got my *** handed to me by the Mustang? I just said I did decent for what I raced. Anyways, stock 15.53, LOL even in Car & Driver stock on ETCs are 14.7, powerbraking and correct settings get me in low 14s. But that's from a dead stop, I ran the GTO from a 35mph roll. The N* peaks at 4k.
And since I know even if you do come down my way you won't ever want to see this in person: watch this. This is a STS (heavier version of my car, un-modded (only mod you can really do is exhaust on these cars) racing a GTO and barley losing.

So you can go by your Manufactuer 1/4 times and I will go by what happens on the road.
