Take the cover off. Numbers wil be stamped on the ring gear. Divide the big number by the small number and thats your ratio.

For example, a 373 wil have 41 and 11. So 41 divided by 11 is 3.73

It depends on what you want to do with the car. Its all personal preference. The lower ratio you go on gear, the smaller therefore weaker they become in the stock 10 bolt.

Sounds like a good combo. Post a dyno graph and the more experienced guys on here can help you more. But make sure you post in the right section..

This would put you right at a 4.10 gear. Assuming you have a stock size tire and were in 6th gear.

Not really 3.73's wouldnt be much difference over stock and wouldnt be worth it, 4.10s are the go to gear with an m6 so that makes sense it would have those

Put rear of car on jack stands, put car in neutral, mark driveshaft, have buddy spin tire one full revolution and count the revolutions of the driveshaft.
Quick and accurate determination.

Yes it was in six gear and the car has 17inch wheels in front and 19s in back so i would think they are 410 cuz the bird is real fast and has very quick acceleration
