UPDATE

Swapped out the SPL diff bushings for the urethane Whiteline bushings. It's a night & day difference! And I think the Whiteline ones are a bit cheaper too. I wish I knew about these before I installed the SPL ones.

Here's the DIY I wrote for my G37 differential bushing install!!

MyG37 - View Single Post - DIY Whiteline Differential bushings

I had Z1 install the white line rear diff bushing on my z last month. They really are amazing. It was a noticeable difference over stock. The rear feels more planted with smoother shifts over OEM. And my OEM bushing was not busted or leaking. I am very happy I went Whiteline and not Energy Suspension.

$2400 from Cerritos Nissan $900 for the subframe, the rest labor :shakes head:

ouch!:shakes head:

Whiteline is no more too =( BUT Energy Suspension front/rear diff bushings for the 350z will fit no problem. Looking at $680-700 with Energy suspension bushings installed

Eh? Whiteline is no more?

HOLEY BUTT SECKS I need to start charging this when I do it, one car and i could buy those sick new spl upper arms.

Edit: Just so you know this only takes 2 hrs and the bushings are $45.

LOL! I'll Nstall these bushings too for $110 an hour LABOR in the STL area. LOL!:D I know @ ~300 rwhp the rear end will not kick out any w/the SPL rear diff bushings installed(based on my Z)!

I did mine yesterday with the whiteline kit, has to shave just a tad off the bushing, mine has been popped for awhile, now kicking myself for not doing it earlier in the summer, car feels and drive WAY better, anyone local in the Pittsburgh area I can handle the install for you at a fraction of the price of a normal shop.

Any kind of verification on this?

It was not the easiest bushing to get out but an angled cutting bit on the air hammer did the job... Cut enough to get the bit between the subframe and the bushing sleeve..kept on hammering through about 3/4 in it popped right out the back. I wasted a lot if time cutting the center out for no reason as well..

ur welcome on the cutting bit, but yeah don't need to cut out the center unless you're using the energy suspension kit

Their site is still active. Z1 Motorsports is out of stock, which is more accurate. :ugh2:

That's correct. Order the whiteline bushings thru Z1 with the Quiafe LSD but the bushings are on backorder unfortunately. Two weeks already and i am still waiting :shakes head:
