Re: 3.90 gears

do you have 4.10's? what are you reving at on the highway in an A4?

not yet im getting my 4.10s installed now so i havent had a chance to drive it yet. theres a gear calculator someware on here and i beleive i should be around 2600 at 75. nothin to really worry about, just run 65 to lower the rmps. no real need to run 75. i drive on back roads so it doesnt really matter to me, thats another reason i went 4.10s.

Re: 3.90 gears

3.90's, like every other gear set, shouldn't have any problems if they're installed right

Re: 3.90 gears

I had 3.42's, 3.73's, and 4.10's in my V6 5speed. 4.10's were the best.. The best acceleration and still get 25-28mpg on the highway before built motor. 22-25 after the built motor. on nitrous 1-5mpg!!
