How do i know if my car has an upgraded set of gears?

1999 SVT Cobra, 5 spd transmission and 285/30/R20 tires.

 

Welcome....I'd go with 4:10 gears with your car!!

 

4.10's

 

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.
