To figure out if your car has upgraded set of gears you can spin your wheel and see how many times your driveshaft spun after 1 full rotation of the wheel. Also a lot of people swear by 4.10 gears which is fine because they're pretty awesome gears. I just recently installed 4.10 gears on my GT and I've couldn't be any happier. It's a huge upgrade from the stock gears and it will not disappoint you.
