Was wondering if there were any options to upgrade the stock open diff that comes in the Auto V35?

I have found that on take off @ a busy intersection the back left wheel will break traction easialy and then traction controll will kick in and everythig slows down. Was thinking that a LSD would help since power would go evenaly to both rear wheels. Have also noticed this when turning right and giving it a bit of stick mid turn

Badluck, but my LSD Diff breaks Traction just the same as yours! Lol

Therefore you turn the VDC off when you're ready to take off from uneven surfaces...

LSD it is for the GT-8 & 6MT...

Best Ever Spec Sheet!!!

Thank you so much Greg :) AAA+++

PS. Do you read/write Japanese?

To do the same and source out a workshop manual in English in any format as I can only find a Japanese CD Workshop after countless searches! :(

vLSD is similar yet different to the LSD that you're thinking. Mechanical LSDs are illegal and these viscous LSDs that we have tend to deteriorate pretty quickly. Grab some Penrite 75w140 and chuck it in until it overflows and she'll be right - for now.

How do you figure a mechanical LSD is illegal?

Also, changing the oil with a viscous LSD will do nothing to help the diff function as it is all contained inside the diff in the silly mega thick fluid in the center.

I know up here that changing from a viscous to mechanical LSD is defectable. I think it falls under 'modification of safety equipment?' Will do some more DD.

Sorry, my mistake. Was mixing up locked vs Mech diffs. Locked is illegal.

Changing the fluid will help it function as it should. God knows when the last time they were changed in these cars was (prior to our ownership). Like any other fluid, it deteriorates and breaks down over time. Changing it helps the diff's efficacy.

Locked is probably illegal, having said that I have been through a full inspection a few times ages ago with a locked diff in a vl and was passed each time.

Yeah, chanhung the diff oil is a good idea, but the fluid that does the work, the viscous fluid, is actually sealed inside the diff center. You can't get to it. The fluid that drains out is just lubrication for the bearings and gears, and has nothing to with the limited slip function of a viscous LSD.

If you make them work hard.. yes, the viscous fluid overheats and loses its viscousity, and the whole thing becomes more like an open diff.

If you just drive them around as your normal 'daily' then it should maintain its LSD function for much longer.

Exactly.. nothing special is required when replacing the oil in a VLSD compared to the standard open diff.

There is a thread somewhere on here where the vlsd centre was cut open on a lathe, repacked with silicone grease or whatever it is, then rewelded back together, seemed to work out ok, better than shimming it solid anyway.

my Y34 is open diff and 6-bolt half-shafts with ABS.

im putting in an R34 GTT helical LSD centre into it. retaining factory final drive so it doesnt throw the speedo out.

if someone puts pics up of the V35 diff, people can suggest OEM replacements that fit (Or can be made to fit).

oh ok so thats why my 350gt 2003 auto coupe sways badly on wet road .very dangerouus to drive in rainy days

feels like left rear wheel wants to move first or faster than right rear wheel.

if u put new tyres at the rear end , left tyre wears out way faster than right side tyre.

checked alignment ,suspension all good but still fish tails on wet road even on low speeds.

I should mention all your V35 rear diff bushes will be flogged by now and leaking silicone grease unless you have had them changed already...

Same goes for the compression bushes in the front.

I just changed my diff bushings today.. 2 front bushes were still ok and squirted silicone fluid when I cut them out. Rear had just started leaking fluid, but still had a lot in it when I cut it open.

Compressions rod bushes are common too.. I took my car for a WA a couple of years ago and they said these bushes were shot. I replaced them with whiteline bushes. The old ones looked ok when I remove them, no splits or cracks, but I guess they had just become too soft..

Yeah I remember that. He used some insane weight (something like 1,000,000 viscosity) of RC car oil to fill the diff center or similar. Said it worked a treat.

What acronyn is 'RC' Josh???

      Its also very clearly made to take business away from https://theskylineshed.com/ which is legitimate and even has a physical address.

      The 'About Us' got me ..  I added something to the cart and clicked 'check out' and none of the payment options in the footer (ie those with buyer protection) were available. Stay the hell away from this one.

      No. Not true for any non-GTR R32. I think even the GTS4 has the GTSt knuckles with eye type lower shock mounts (as opposed to GTR fork lower shock mounts). The only R chassis in which something like the quote claim is true is the R34, on which the turbos have the fork type and the NAs have the eye type. **Edit: Actually I reserve the right to be wrong about the above statement. It might also be true on R33s. My memory on those shitboxen has faded too much.

      It's a scam. It has all the telltale signs: - The "business" doesn't have a physical address or really any kind of information listed - It's using a generic online store website template - The prices are ridiculously reduced. To good to be true cheap - Everything is in stock and can be ordered in any possible combination   I've seen a few of these for other products as well. Things like sunglasses for example. I'd say stay away from it! And maybe reach out to the real theskylineshed and let them know this exists. I doubt there is much they can do about it, but still.   I don't know if they would actually take your money if you ordered something. Or whether it is just for collecting credit card details to scam otherwise. I'm not game or stupid enough to try it.
