Hey guys, Just wondering what kind of gains i should see with the 4.10s installed in my M6. I was gonna have them installed this week but the guy said he cant get to them until august 1st or so. $375 but hes supposed to be extremely good and a perfectionist so he wont let the car go if its not just right. Anybody have e.t. 's before and after gear install.

Anybody?

 

tire expense

 

I dropped 3/10's with my A4 car. 60 Ft. went from 1.9 to 1.7. You'll need GOOD tires. I'm running ET Streets

My '96 Z28 came with an M6 and the factory 3:42's. When I killed 2nd gear, I decided to go with the TH350 and vigilante. This took my sixties from a M6 effort of 1.9's to 1.6's. Meanwhile, my good friend took out his 3:42's and put in 4:10's. He also went from 1.9's to 1.6. I was amazed. Both of us run M/T ET streets. He gets the same sixties as I do plus he has all the efficiency of the manual tranny, meaning he pulls HARD at the top end of the track. I still have my wounded M6 and I plan to rebuild it and go back with 4:10's. You'll love the change. DO IT

 

3 tenths is probably a good estimate

 

This is what i dont get...you guys say 3 tenths..but that is also with drag radials etc...how many tenths would u gain with et streets without 4.10's? As for street racing would me going from 2.73 to 3.42 have any great impact? I dont want to spend a boatload of money on gears when it could go to something else?

Thanks guys.

 

I dropped 3/10's with the SAME tires

Thanks you didnt specify that you used the SAME tires you just said you needed GOOD tires lol. Would i need to upgrade tires going from 2.73's to 3.42's? Because i get some spin now...but not much.

I just realized you are in the maryland crew? What track do you normally run at Cecil? And are you a member of the EFA?

 

how do 4.10s affect you guys MPH.. did it go up or down?
