I was gonna put 3.70's in my 9", Its a street/strip car and not a daily driver.. What would be the best gear 3.70, 3.89 or 4.11's? I have a 2800 stall and shift at 6500 and dont wanna go into od in the 1/4.. Also trap 120-122...

 

4.11's.

 

+1

love mine compared to 3.73 last car - but that was more a daily driver

I drive 50 miles a day just to/from work with A4/4.11 and it's sweet

3000 rpm at around 75 mph cruising
