Usually 3.73's for A4
and 4.10's for M6

 

whats a popular gear for lt1s autos...mods in sig right now i have 3.42s. Should i stick with them or more gear, also i plan on sprays in the near future

 

would it be a huge jump from the 3.42s? i mean would i notice them

 

I really can't speak for the 3.73's... but when I installed my 4.10's the smile didn't leave my face for a long time. It really woke up the car & made it a blast to drive!

I'm sure other's will chime in who have A4's with the 3.73's.

 

Well I went from 2.56s to 3.73s in my Roadboat and I think the smile on my face didn't go away for like 8 months. It literally made my car feel 1000lbs lighter when it was accelerating. If I didn't drive on the highway a lot, I would have gone with 4.10s

good stuff....but i'm wondering with my traps of 109-110 on stock tires.suspension would more gear help ? and with a trap of 123 (n2o)

 

If you're having a hard time hooking up, I think more gear would hurt cuz you'll be turning the tires more and creating more traction problems. You may also want to think about the power band of your cam. I do not know the power band on the CC305 but with a 4.10 gear, you'll reach the top of your power band sooner and change gears. With a small cam, you could run out of gear with a lower ratio.

 

well power seems to come on after 2500 til about when it shifts at like 6k+

 

Thay told me the same thing. please listan to me and put 4 10's in your auto

 

yeah i was either thinking 4.10s or more stall

 

4.10"s and more stall
