I'm going to be upgrading to a VLSD tomorrow and have the choice of the 3.5 or 3.7 final drive. The 3.7 is $300 more than the 3.5. Im currently run a 3.5 open diff N/A. My question is, for $300 are the 3.7s worth it.

Get the 3.7, your car will be faster.

 

^ What he said

 

the higher the number, the faster youll accelerate, but your top speed will be a little lower, dunno how much time you spend above 120mph but something to consider.
youll be at a higher rpm when your on the highway so a little less mpg too

 

I would do the 3.7 , and whats the deal with the gearset for $300 PM me details. I need a set.

 

Get the 4.08 from the Frontier.

 

 

lol^

if you plan on staying n/a get a shorter gear. if your going to go f/i keep the 3.5.

i hear great things about the 3.9 and 4.08 but your rpm @ 70 will be around 4k

 

^^ try again

 

ya, im curious of the details too........

I'm in the process of helping a buddy install a 3.7 diff into his Z with a quaife...

is it purchase one pumpkin or the other? or how are you getting it?
