How much quicker would u guys think i would be in the quarter with 4.10's????

 

Completely dependant on your ability to hook it.

 

in an ideal world........where everyone has traction (what would u think i could grab??)

 

Probably cut almost a second off... But your car will be a bitch the rest of the time.


I would only do it if you're serious about turning the car into a drag race only car. You'll never get a good kickdown from freeway speeds and beyond ever again. The car will be faster through the quarter, but it will lose a lot of what made it fun to drive IMO.

 

personally i think is too much gear for an A4 car. the deepest id go with an A4 is 3.73, and since you already have 3.23s i think youd get more bang for the buck out of a torque converter.

 

An effective converter and 3.42's would be my suggestion.
