What happened to the group buy thing then ? I wouldn't mind one for my Z31 !

Well, I'm gonna ask my Nissan dealer again, see if I can get prices out of him.
This diff issue really does my head in... My Z only does about 5000 miles a year so a welded diff might not be so bad. I've heard Quaife's can be a bit unpredictable & to be honest I'd rather stick to a clutch jobbie.

That confuses me
If a car had 500 hp (I wish lol) would it not break away a lot easier?
I.e. looking at it/the vid .... If a std 240 made 140bhp @ the wheels, both wheels, would spin as there’s not enough power going through them?... but if you look at the same vid again ... but with 250 bhp this time.... surely it would break away on one wheel easier this time

I think you need to go back to basics and try to understand exactly what is happening inside a plate / clutch type LSD.
It was plain to see that your LSD wasn't limiting very much of the slip - ie, one driveshaft was spinning more than the other. That - to me at least - indicates a fairly low breakway torque setting. It has nothing to do with power or torque over and above the amount that is needed to get one wheel spinning; everything else is about the LSD setting at that point.
These things are difficult to explain in words on a forum like this. I could do with some models / cutaway examples in front of me to help explain what is going on.
One question: did you check the LSD clutch / shim packs internally before bolting the diff into the car, and/or did you check the breakaway torque setting? ( and I'm not talking about what somebody 'told' you........ ).
And I'm not saying that your LSD is 'faulty' or anything like that. I'm just pointing out that its 'limiting' of slip is quite benign from what I see. I'm sure you are quite happy with it. After all, your car is not a race car..........

If I’m honest …. then no. I was informed (not told lol) no mods would be needed for my rd use. I didn’t adjust anything as I was advised to leave it as is. I was given various spare plates, so adjustments could be made if needs be. Not that I would know how tho, n I deffo dont want to take it apart atm lol

Fair enough. But you take my point? I don't think your diff preload is set very high, and even if it was, the treatment you gave it with your Santa Pod donutting would probably have loosened it off a fair amount.
I was trying to remind us all that talk of what diff / LSD is "better" is subjective nonsense unless the ins and outs of each type are fully understood.

Count - are you taking the pith ? Remember the 10 maths of the Z ? I had 8 of them and asked you for the last two ? I sent you the list and.....

It was just that...since I had your attention !
You should know Count, it came via you - isn't that where you get them from ?

I see, the word 'straight' disturbs you. Ok, the diff was sold to me by the Count who sourced, bought and imported it from Japan.
I did not get it 'straight' from Japan but via the best, most reliable source known for quality, hard to find genuine Nissan / Nismo parts in Japan.
In no way did I mean to infer that I had used my own initiative to obtain such parts - my apologies if that was how it appeared !
