Im thinking of getting some 4.10's for my 00 gt but i want to know what the top speed would be with a t45 tranny, also i was woundering what the 80mph rpm's would be. if any one can help let me know. i dont want to waste money with 3.73 or 3.90. so i think 4.10 is the best, i still drive the car on the street once or twice a week so gas millage isnt the problem.

80 is about 3000 RPMs with stock tires

we had the rpm calculator up before but a mod took it down. it was pretty helpful for these questions. 4.10;s will actually imrove your city mileage

if you can reply with the gear ratio's for the t45, the wheel size, and the tire size (e.g., 235/45 etc. ) I will do the math and post the exact results

let me know

so with patience with 410's in 5th @ 5,000 rpm you'll get 150 mph
hmmm
