I've noticed this for a while now, when putting the power down around a corner, the car would rev a touch higher and would jerk around. I am not breaking traction, nor am I going sideways.

It almost feels like the clutch is slipping, but I've had that replaced about 1000km's ago with a ceramic plate jobbie, that fixed up old mr slippery-launch!

Now when driving, changing lanes while putting the power down, the car flicks-back into the other lane quickly, almost like I'm recovering from traction loss.... But i'm not.

I put the car up on jacks (the entire rear-end) and noticed how the wheels spinned when i turned them manually.

I can turn the wheels in any direction and the other wheel will follow suit SLOWER. I can also hold back one wheel while I turn the other. The drive shaft is still turning when I hold one wheel back.

It is obviously a touch stiffer when I hold one wheel back, but I can still turn it. I thought an LSD was supposed to force each wheel to turn the same etc ? and you can't hold it back ? (can you?)

I've recently replaced diff oil with Castrol LSX90 (the best stuff for LSDs apparently)

What is happening ?

What usually wears out on a diff to make this happen ?

How can it be fixed ? Can I just take it to a Differential specialist and tell him to weld it locked ?

Cheers Guys,

-Kym.

mine does the same, im not to sure what it is... just how it feels like your flicking the arse end out but u haven't broken traction in the first place. I have a feeling that it was something to do with the 4 wheel steer. Thats a guess, but thats what I was pointing towards

hah kym i have the same problem i think

well mine - the car kinda 'wanders' when i change lanes

think of it as high winds blowing the car and you can feel it slightly swerving in a way

sorry im not good at explaining

however, i wanna get rid of HICAS as problem is definately caused by it (HICAS warning light comes on regularly)

from what i know, if your doing one wheel burnouts, its a open diff, which either means thats what it is in your car, which is un likely, or your lsd is going bye bye, myn gives bad feedback, makes horrible clicking noises, and chooses when it wants to do 2 wheel burn outs, ive been told it is on its way out, and some say its the way it is.. ohwell.. if anyone knows were to source cheap GOOD diffs, sing out

afaik the R33 GTST has a viscous LSD , not a mechanical as per a GTR.

Viscous relies on silicon gel to heat up caused by a different turning rate in the axles.

If the diff is a bit old , this may take time to react if it does at all.

The waving or lane changing is more related to w/alignment , tyre pressures , shot tyres or slack bushings.

What you have to realise is the hicas works in the same direction as the front wheels above 60kmh ( or so ) and only move by 1 or 2 deg anyway.

Cheers

Ken

    • I can ship Nismo floor mats to you: https://www.oemsoko.co.jp/products/nismo-floor-mats-for-skyline-r33-bcnr33-stagea-wgnc34?_pos=1&_sid=9278c1467&_ss=r  
    • Here's the link: https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6642/misc/G49?frame_no=WGNC34-137122 What you think about it? The same product i found on nengun: https://www.nengun.com/oem/parts/40567/MiPwn5qAMfCfmpxHNDnwn5q9MDAx8J-QiW9sZC1qcC0xMTAtRzQ5LS0wMDE/Floor+Carpet+%2F+Mat+2/0688339eba149c19 Bot i have spoken to 😅 ensured me, that mats are 100% original, oem product. I have my doubts. I also heard what you mentioned, that nengun often offers items that are actual not available... On the other hand mats i found on japanese yahoo or ebay are in poor condition and still quite expensive so i'd rather wait for some better offers. My location - Poland. We literaly don't have ANY market for used Stagea parts so need to search outside Europe.
    • You can’t see much on the other side as the lcd is there I don’t think it’s the same as the m33 beside it as the markings on top is not the same was hoping someone had a good quality photo or if they just happened to have the unit in hand, quickly take the cover off and take a photo to clearly show the marking on top to identify the diode   the unit is currently with an electronics repair shop so I can’t take another photo at the moment hopefully they are smart enough to know if it’s a zener diode or not
    • I'd be very surprised if you can buy new OEM mats. But if you can, I want some too!  Do you have links to the variations you found? Also, where are you located? I found that Nengun is happy to list items to purchase but when you do buy them you'll get an email that it's actually discontinued. As far as I know the variations in floor mats are different colour schemes as well as automatic and manual having a slightly different shape. The automatic ones fit into a manual car without issues, but I think you'd have trouble fitting the other way around. I have photos that show the shape difference if you care. FWIW I bought sets of used floor mats in decent condition at yahoo auctions.
    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
