So what's the RS5F31V viscous LSD gearbox setup like in a turbocharged micra?
I've had enough time to fully evaluate it now, so I thought I would post my honest gut feeling impressions of how it performs.
I would sum it up as this:
Besides those points, I wouldn't rave about it comapred to the previous single spinner setup. I can notice the higher threshold before the wheels spin a bit. The thing that smacks you in the face is how it pulls so hard when exiting corners. Apart from that, its honestly not a huge black and white difference like you might have thought.
I can still put my foot to the floor and light up the wheels all the way through second gear if I choose to. Yes I'm running garbage tyres and maybe the camber could be flattened out a bit more, but I had these same tyres and camber settings before the VLSD went in. So I'm measuring the difference pretty fairly.
One key thing I think is: The VLSD still has a slip threshold. I.e. with enough torque it will induce slip anyway. I think that's one issue with my car. Its putting a fair bit of power through it, I think for example in 2nd gear when my wheels are spinning, that it even possibly could be just one wheel if the VLSD is slipping due to too much torque.
Yeah I'm glad I got it because it handles better and pulls harder. But its not the super perfect solution to getting off the line like a 4WD kind of thing.
I think installation of the NISMO mechanical diff centre would remove the slip threshold that the NISMO diff has built into it. I think the mechanical centres are a lot more hardcore. I might get around to trying that one day, but they're not cheap.
Hope this is useful for anyone considering tracking one down.

I would sum it up as this:
- In the wet threshold before wheel slip is moderately improved. This can be noticed reasonably easily.
- 1st gear launch ability is fractionally improved. Nothing spectacular, but it does get off the line a tad better than previously. 2nd gear traction honestly doesn't seem any better to me.!
- Exiting corners: This is where the VLSD really seems to excel. Whichever way you are pointing when you hit the throttle it just locks and off you shoot in that direction rather than the inside wheel doing a burnout. This is a great advantage of the VLSD.
