Well, at 6'3" 250# I guess it would be worse for me.
I'm surprised to hear that, because they should have room for a helmet to be worn.
I'd think that they would want to make the driver's seat and the associated leg and head room accommodating for as wide a range of body sizes as possible!
I like the looks of the 05-06 GTs better too. Far truer to the original.
I like the 05-06, would love to have one, more than many other cars, but I would want to be able to get more power from it than stock, given the horsepower wars of today leave the power output of that supercharged engine falling behind. I would imagine that there is aftermarket performance parts support for it, like pulley and injector upgrades, and maybe programming for the ECU.
A nitrous + fuel injecting unit at the intake of the supercharger would seem to be a given. I'd expect the supporting components (transmission, half shafts, etc.) to be strong enough to handle the increased power.
