Yes, I've done the calculations and they won't shift that much which works for me. I do A LOT of hwy driving which is why I don't want the 3.9 or the 4.08 rear. I'm mostly interested in this to compliment the aluminum driveshaft I will be ordering. If I can find the part for cheap I am able to do the install labor myself, so why not...

 

Ken, sup bro?

You're one of the many on back order for the Z1 DS huh? I'm really glad Frank ordered it for me when he did a few months ago cause that mod was really worth it to me.

Also considered having Hill's install 3.9/4.0 and he actually discouraged me from going 3.5 to 3.7 for the reasons people above mentioned. but hey if you doing the install yourself, what the hell why not. Hill's will install a turbo next summer so I decided to stick wit the 3.5. You still go to the NGC meets?

 

I daily my car, approximately 3,000 miles per month. 3.692 final drive will be more than sufficient to achieve what I want without the sacrifice in fuel economy. I do all my work myself, the only thing I can't do is tune.

I attend many NGC meets if my schedule allows. Wish I weren't working today. I was really looking forward to the fall members meeting this afternoon.
