you won't be dissapointed

 

4.10+M6=no traction=fun
4.10+M6+315 tires (or 275 Drag Radials) =2xfun=2xpower

I had 4.10 in my Camaro and now I have 3.42 in my TA. I liked my 4.10 when I was in 2nd gear (and the traction was there), but 1st is totally useless (you can’t punch it without going sideways). The Camaro had much less HP and TQ than TA but it felt 2x faster in first 2 gears...
If you will be using nice set of tires (275 at least), you can do 4.10 but for regular 245 I would use 3.73. You will loose to any WRX or Evo on the street, cuz you won’t have any traction in 1 and 2 gears...

i had a similar setup to yours in my car. had the 4.10's even before the heads/cam swap. i just never grew to like them for some reason. im definitely going 3.73 next time (or less even). gas mileage wasnt the issue. jmo

 

Man I cant make up my mind! I almost hit the buy it now button on a set of 4.10s on ebay but i cant make myself do it! RAHHH!! Its a hard choice. I have already bought a Zexel diff now i just need gears. But i have a 3.25 posi geared 9-inch center section i have get CHEAP and the gears, diff and istall kit with set-up are half the price of a 9-inch housing from Moser!! Dang it a tought choice.
