Not gonna lie. You are making me nervous

. Taking away my excitement. But, its all good.

The shop I took it to is Full Throttle Performance in Rancho Cordova. Looks like they are specialist in Nissan and Infiniti. He is the same guy that installed my Z1 anti starve kit.

I think Wavetrac is 1.1 way. I dont know exactly. Maybe someone can chime in with the info. I would guess its similar to Quaife. As for break in, there shouldnt be any. But im taking it easy for the first 300 miles.

Wavetrac is a mechanical gear type, not a clutch. This type of diff is also called a Torsen (Torque sensing) with Quaife being one of the bigger makers.

in general a torsen will send power from inside to the outside in a corner through the gear mechanism, but it relies on both sides having grip. If one tire does not have griff it will not lock at all and is an open diff

Wavetrac has an added design that counters this (Google, there are diagrams) so that even when one wheel slips, there is still some lock and power will be transmitted to the wheels.

It does not lock as hard as a clutch type, but requires much less maintenance and doesn’t need a diff cooler. This makes it above open diffs, OEM VLSD, or a quaife, but below a clutch type in raw power. It will also be quiet

So a small update. Ive put about 110+ miles on the new lsd. It is amazing. No whining or any noise. It feels very similar to the vlsd for daily driving. I have a track event coming up in Sept. So I cant wait to test it out.

OptionZero - When I was shopping lsd I was considering the OSGiken, even Z1 said I should go with that. But it seemed like alittle more work for me. So the Wavetrac was right up my alley. Low maintenance and better than the vlsd. Someone had mentioned the car should have came with this. And I cant agree more.

Yes, a number of our veteran users here have OS Giken. Check out the track section and search for "giken" and you should get a bunch of feedback.

It does heat up so it needs a diff cooler. Hardware isn't that bad it seems, but some wiring is needed. You can do an on/off switch or attach it to a temp sensor to trigger at a certain mark. All told, it's another $1,000 on top of the diff, plus you have to use OS Giken fluid and change it every year or so.

Performance wise, it's awesome, but effort is high.

Wavetrack is a compromise. Drop it in, no cooler needed, fluid doesn't need to be swapped nearly as often, and streetable.

I have a VLSD (came with the nismo), which is fine for now since I'm still learning. Next season I will look into stepping up to Wavetrac or OS Giken.

I think I saw you at Thunder Hill - were you at Speed SF earlier in July?

I was out on Thunderhill in June. In July I went to Sonoma. I signed up for 09/01 with Speedsf. I usually go out with SpeedSf or Lightspeed. You should come out. It would be cool to have a fellow Z out. I occasionally see Zs out on track but never get a chance to conversate.

I've got Sonoma on 8/3, i forgot that it's actually closer than T-Hill and very fun from what i remember. I was there 10+ years ago in my S14

T-hill is wierd to me. The turns don't flow together in my head as easily as Sonoma did - i think i played Sonoma so much on Gran Turismo, I picked up the rhythm much more easily

Buttonwillow is the one that totally messed me up. It felt so flat and clunky

You are going to like Sonoma. After the repave its so much better.

Thill is one of my fav tracks. Its fast and technical. My top has to be Laguna Seca. Which im trying to get to before the rains get here.

Love it! Wish I could afford!!!

So while the Braum seats are nice and all, you do get what you pay for, I'm seeing some wear on my driver seat after 6 years? (damn i guess i've had these for a while). So I will be re-installing my stock seats once my dad brings the driver seat from their house.

I ordered the CZP shifter boot collar ring which im amazed and glad they decided to do a 3d printed solution. I have a brand new OEM shift knob coming in because i'm just feeling very boring and my original one is long gone by now.

I also have brake fluid and coolant fluid tester kits on the way. I'm sure i need to replace the coolant, but I'd like to just have those tools on hand.

I'm not sure about the yearly oil change in OS Giken LSDs. I have one for 3 years now. I did the first oil change after 500 miles, as break in procedure. The second oil change was then done again after a year, because I swapped the final drive. Next change I plan after 20K miles or so.

Also, OS Giken themselves are saying this:

Quote:

Fluid changes at normal factory intervals: OS recommends the first fluid change after 1 event or 500-1000miles in order to flush out debris left over from the manufacturing process. Subsequent changes are recommended at the normal factory-recommended intervals. Quiet/composed for normal street driving: Since OS LSD offers smooth, progressive locking up to 100% with a low amount of preload, it will feel like an open diff at slow speeds, but will still efficiently transfer power to the ground under load.

abm89 · 07-31-2024, 04:15 PM

GoodNewsEveryone.futurama, I checked the coolant quality with one of those test strip kits and the levels look great! So I will hold off on doing that maintenance. If it aint broke, don't mess with it.

I also received my digital brake fluid tester and the brakes are still good, which was expected since I went to the Z1 calipers last year. The clutch fluid needs to be swapped so I'll work on that this weekend.

Sidenote, I'm glad i went with yellow for my new brake calipers. It gives the car an original look. They clean up really well too.

I picked up my R200 housing from diff specialist today. OS Giken LSD hiding inside. I decided to deal with the extra effort because sliding the car around is occasionally important to me and I don't mind changing fluid more regularly.

Can't wait to get it bolted back in and rip some skids (on the track). Car's been on axle stands for a number of weeks now sorting things out and waiting for parts.

You will enjoy it. Make sure you use the OS Giken diff fluid and it will not act clunky.

abm89 · 08-02-2024, 11:12 AM

I want to put an OSG in my car, but it'd be a waste considering i don't really track it anymore.

What's not a waste was the effort spent on putting my stock seats back in. I'll contact braum about a re-upolstery kit, if not ill take them to a local shop to put some quality material on them. I also managed to install the shift boot collar and stock shift knob.

The upside is that i'm almost down to zero DTC codes, just the power steering pressure switch and the passenger airbag off light. The latter is because the dash was taken off so many times that the harness broke. I need to find that connector.
