there is a 4% difference between 3.9 and 4.08 - and a $200 price difference, and the nature of waiting for a special order - IMHO, not worth it, but it's a decision you need to make for yourself. Your money but the factory gears being what they are, it isn't worth the price of admission (to me) to swap in ones that are a measly 5% shorter....especially on a car that wants to rev like the VQ. Heck in my car, I run 3.9's now, built NA VQ35, redline at 8400, and I'm swapping them for 4.3's because the 3.9 just is not enough anymore

the 4.08 is perfect for the VQ35HR (2007-2008 350Z), and even more so for the torquier VQ37HR
