Rear End Gear Ratio

[t walgamuth]

What is your final gear ratio in your tranny?

My car has the six speed Tremec with a .5 sixth gear ratio and a 4.10 winters rear end so my final drive is 2.05. I imagine I'll have all the gear I want for acceleration or fuel economy.

I run the 3:77 in my Factory Five Coupe and with my transmission I have more acceleration in 1st, 2nd, and 3rd than I can really use. If I mat it the tack pegs before I can get my foot off and slow down. But 4th and 5th are really good for driving down the road.

I went from 3.46 to 3.15 gears in my 527hp SBF using a TKO-600 and still lite up the tires in 1st, 2nd or 3rd if I am not careful..... FYI tire O.D. is 25.9"

If you go too low in the rear you may render your 1st gear useless. Who wants
a granny gear...not fun.
