0-60 1/4
2006 Subaru Impreza 22B STi 4.7 13.5 (Car & Driver)
We all know what GT's will run~7.5 15.5 (Assuming your stock and being generous)
Srt10 Rams with 500hp run around 5.5 14.1 (times that i see them run at atco )

If a 500bhp Ram can barely dip into the 13's you still wouldnt be a Sti and neither would your GT. Unless you can post a video of under the hood of both of the cars and then a victory for you car in a 1/4 mile race from a dig, everyone is going to think youre a liar.
