new car, mystery gears I just bought a 94 z28 m6, and I don't know much about it. It's kind of a mystery car. It has mods, but I don't know what exactly. I think it might have gears though.
It has stock 16" salad shooters, with stock tires. I believe they are 235/55/16. It made the following #'s:
1st gear 2000rpm: 15mph
2nd gear 2000rpm: 22mph
3rd gear 2000rpm: 32mph
4th gear 2000rpm: 41mph
5th gear 2000rpm: 54mph
According to my calcs, the car has 3.73's out back. Can anyone else confirm this or back me up?

Jack up the rear end, put it in neutral and spin the tire around one full turn. Count how many times the pinion yoke/DS spins. If it's 3 and 3/4 turns it's a 3.73. I would use this method if it's a mystery car and you don't want to pull the cover off to count the teeth.
