I may be reviving dying thread, but some of the terms used in these kind of threads are unclear to me. when people talk about swapping pumpkins(differentials?)are they simply referring to carrier assembly, or are there other parts necessary? can i simply swap my base auto carrier with the mt vlsd carrier and then install the 4.08 gears

You posted on 2 threads,, I gave a description on other one. Also can call Z1 Motorsports & confirm needed parts for swap

Whats need to run a wavetrac and what slave ill be running a bp performance kit so external is not a option

WaveTrac was not available. I had the OS Giken installed. It is very quite for a clutch diff. My car will come off a corner now like never before. This should be number one on the upgrade list before any suspension work.

I tell people this all the time and they say they want to wait or it's not worth it...well I waited to do when I did my final suspension upgrades and was pleasantly surprised at the difference it made and would have made it one of my first suspension upgrades with hind sight being 20:20!

You and me both. I feel stupid now.

Here is an update on the OS Giken. Yes, it can get clunky on ya with warm RE11's and tight turns. I am running Motul 75w140 fluid. I may try the OS Giken fluid later if it get's on my nerves.

B&W_Evader · 08-22-2017, 02:46 PM

Mine only makes noise when I'm driving normal, slow sharp corners, never when I'm pushing it.

OS Giken or Quaife for DD Automatic TT 370Z, which one is better for this scenario?

I have the Quaife in my base/touring,,,as i'm thinking it was about my only option with the factory 3.357 gearing.
I was told that if you lift a rear wheel (teeter it) while tuning up/down pretty sharp incline/decline...that the lifted wheel would only pull. As a Wavetrac unit won't do this.
Quaife is helical & no maintenance/while OS Giken is conventional clutch type & probably require a bit more frequent oil changes.
Gotta see what's available for your's.
My Quaife will draw even black lines as desired & make's 0 noise.....but i'm sure an OS Giken can be shimmed up tighter & potentially chirp a tire on very sharp turn's,,,as it's a more True posi unit.

shadow85 · 09-07-2017, 09:15 PM

CZP and Z1 have both stated Quaife is the best for me. RevZone here in Australia reccommended Cusco RS 1.5 over the Quaife because the Cusco is a full mechanical where as the Quaife is a helical. Not sure if they are just trying to sell me the product because they have them readily available.

I may go with OS Giken because I can get it much cheaper here locally including the Output flanges.

Hotrodz · 09-07-2017, 11:26 PM

Cusco is a damn good rear diff as well...Quaife has built rear diffs for F1 cars so you can't go wrong with any of them.

Hmm such a hard choice here, lol.

Cusco RS 1.5, Quaife or OSG!?
Guess ill just get whichever I can get cheapest, they all seem to be pretty highly rated.
