I don't even know if this is possible, but can the front open diff of SG -> Foresters be replaced with the vLSD unit from the rear diff?

Has anyone done this?

If so, what sort of costs were incurred / benefits achieved?

How does it affect handling, on-road drive-ability, off-road capability?

I am slightly interested in this, but not interested in going down the kind of path that Venom has with his Liberty. For that sort of money, I would be more interested in upgrading my camera body ... :iconwink:.

If it is possible, it seems to me that it might give some of the benefits of the full monty, at a fraction of the cost.
 
Funny, I've been wondering the same thing, having a plated rear diff & a vLSD front diff. That would be awesome!

I did a search here for this, but couldn't find anything.

Even without a plated or helical LSD in the rear (just the standard SG vLSD), I reckon it could possibly improve things quite a lot.

However, perhaps the vLSD might not be able to handle things when attached to the steering wheels?? Both the other vLSDs are operating in straight line situations.

What's your reasoning for this, mate?

I would have thought the constantly changing relative velocity of the steering wheels would put more strain on the diff rather than less?

I don't know, though; and very interested in all and any thoughts and opinions on the practicalities and everything else of this.
 
No it won't physically fit, also the stubs for the driveshafts are different on the rear to the front.
I have already looked into this. Benefits would be better cornering onroad obviously, but unless you drive quite hard it really isn't worth it.
You could always fit a helical type up front, the cost would probably only be abit more than $1000...

Thanks for your various inputs to this question.

Seems that the only way to go is with the various plated etc diffs.

Like I said, I would rather spend the couple of grand on a new camera body in that case.

The main reason I traded in Roo1 for Roo2 is that Roo2 can take me to more places, more safely, than Roo1 could, so that I can take photos ... :iconwink: :).
 
If you read Venom's thread, his plated diffs have made a huge difference. But they are expensive!

Taza, if you can afford it I wouldnt even consider a torsen over a Cusco...just no comparison. The torsen is the same as an open diff once a wheel is lifted while the Cusco is getting near to a locked diff.

Does Cusco require maintenance/readjustment?

The benefit of the Torsen is little to no need for maintaining it which is a huge benefit for the front diff. Rear isn't so big a deal.
 
No, plated is not the only option. I have a quaife front diff, helical or gear type. Love it.
 
You have to brake with the left foot to go forward ! It does really work !
 
so far so good. Haven't had a wheel up that much since I got it, but my theory is that when I do, the rear lsd will get me forward enough to get that front wheel down again.

I have noticed an improvement in wet conditions on road, and in cornering. The car feels like a limpet at times.
