Hi,

I'm just curious to find out what sort of difference the rear axle ratio would have on 0-60 or 1/4 mile runs with GTs equipped with a 3.15s and 3.55s rear axle ratios? Is there some sort of formula that can be applied to figure this out or is there some data out there? I'm just curios of the effect of a RAR on times


thanks

 

I haven't seen any tests or data but you might see a .1-.3 increase in your 1/4 mile times. Probably not much in the 0 to 60 run.

 

For any intrested, I found this article... a 3.15 Auto vs a Performance package Stang.

To my shock, the auto was slightly quicker! I'm guessing the manual maybe didn't have the best driver out there but still... interesting

Why the shock? Autos are always faster.If the test car would have been equipped with the 3.55 gears the difference would have been significantly more.

 

I know that I had 3:15s in my 2012 and the 3:55s in this car make it a rocket! I almost don't need 1st unless I'm on a hill. I do find myself in 5th more often than I used to but man, cruising to light speed is a toe-tap away!
