ok like my old cars i would go from 3.42 rear end gear ratio to 3.73 and 1/4 mile was cut almost in 1/2 SECOND. then went to 4.10 and from 3.42 to 4.10 1/4 mile was cut about a second

has anyone did rear end gear ratio changes on these cars?? i have a 6 speed.

WHAT IS THE STOCK REAR END GEAR RATIO?

btw i have a g35 but i know this car is about the same.

 

do some searches...quite a few of us have the 350evo 3.9 ratio (stock is 3.54 on the 6 speeds)

adam

 

Auto is a 3.3
manual is 3.5
350EVO.com 3.9
This is what the track model should have come with.
