Sorry guys, I just noticed that the part number is listed somewhere already. Managed to find them eventually.

Dthem, can I confirm a couple of things:

I have a Sports 7AT with VLSD. Can I buy a manual open rear diff without VLSD and transfer mine over? Or, if budget allows for me to purchase a Quaife, can I install it inside the manual rear open diff that comes without VLSD? Or must I buy a sports manual rear diff with VLSD? I'm about to make my order so I just want to be sure.

Thanks!

Hey guys I'm new to the forum and got a '12 370z sport 6spd and wondering if you guys have had any problems with the spacer 38154-0c000, I'm currently in the middle of doing my 4.08 swap with the list that Jnaut provided and wanted to make sure it's the correct spacer before pressing everything back together

Old tread, first of all thanks for the info from all you guys.

I know its been a long time since some of you installed the 4.08 gears, but I wanted to ask you about having a lightweight flywheel + 4.08 gears combo.

Does the car feel "too responsive and jumpy" for DD? I want to do the 4.08 gear upgrade but in the future i'll also do the lighter flywheel so maybe 4.08 is not the best option for me, maybe 3.90?

what's your input on this?

thanks ahead of time

I have the Southbend 13lb aluminum flywheel, 4.08's and an NST lightweight crank pulley and the car is VERY responsive but I wouldn't say too responsive. In all honesty, each of the listed mods aren't THAT noticeable by themselves (I did one at a time) but together that make for a nice bump in the cars pep. IMO the flywheel, pulley and gears all compliment each other. if you're doing gears, go with the 4.08's...I doubt you'll feel much of a defference with the 3.90's. Definitely not "too jumpy" when paired with a lightweight flywheel.

Do you have SB clutch as well? How many miles on the flywheel? Any issue?

Yes, I have the Southbend Stage 2 clutch paired with the flywheel. about 10k miles...no issues whatsoever.

At one point I had: JWT 16 lb flywheel, Stillen crank pulley, and 4.08 gears. Not too responsive, just fun to drive. Do it.

Looking for info. I have a auto with stock vlsd. Will a g35, g37 manual with stock vlsd differential work with the swap?
