I would do it and not look back... Completely better car in every way, makes the cobra feel like a second rate car, but considering they are more than twice the price new that's to be expected I guess. Not as violent up to about 100 miles an hour, (but still much faster) because the power band is so much smoother. It just gets faster and faster all the way up to 7000 rpm and feels like it could go forever. It's sneaky fast, one of those cars that when you check you speed thinking you may be at 80 and you're already at 120 its a surprise.
Nice pickup man. I sold my Procharged 10 sec. Mach 1 to get an 08 Z. I agree with you on everything. I still love mustangs and will own a Terminator one day, but the Z is in a different class.
Damn yours is low. Aftermarket lowering bolts??
