Ok.. obvious to most the sheet metal changes are interior are apparent.

Where else are changes?
After speaking to the Ford people at Ricart in Columbus..

ALL V6's are more like Gt's ( or at least Pony pack V6's ) when it comes to suspensions.
As most know V6's had a single sway bar and 16 inch rims with tires rate for 115mph.
Pony packs V6's had a thicker front sway bar, An additional rear sway bar, and 17 ich rims with the same ZR tires on the GT Stang.

Now ALL 2010 V6's have a front and rear sway bar.. heavier springs, struts, 17inch rims and better tires... now as far as i know Pony packs will only have fog lamps, emblems and stripes with chrome tip exhaust over the regular V6s.. otherwise All V6's will handle much better.

2010 Gt's are more like 2009 Bullitts..tuned and more balanced.
Fords gonna hurt some aftermarket people here. They come with CAI from the factory. They also dont require a tuner to go from 87 to 93 octane! - The computer senses and makes timing changes same as the 09 bullitt .. 2010 Gt's have better front to rear weight ratio just as 09's bullitts compared to 09 and older Gt's which improves launch and handling slightly. 2010 Gt's come with heavier suspension as well.
