For specifics on the LSD better to contact Tom, but I think not much customization was needed to the quaife unit to make it to fit the stype.
It works pretty well with traction/control / DSC, as that one only comes into action once a wheel is actually spinning, and that only starts after the ATB (Automatic Torque Bias) type diffs do there work first.

I don't know how the Jag's system works with the standard differential but I thought I'd raise the question. With the Quaife installed it's going to slip less but you're still going to have differing wheel speeds and some slippage anyway. If it doesn't slip at all after such an install that would be terrific!

They will know Tom, not sure if they can help with the diff. Just contact Tom I would say, here is his email address tom@tljaguar.co.uk

If I'm not mistaken it wasnt Quaife that did the installing and testing of this it was another shop overseas. It was Tom Lenthall at TLJaguar that got it to work thats why I was curious if they worked with Quaife to develop an LSD for the Stype or if they used one from another car and modified it or just installed plug and play into the Stype. If they did the one from another vehicle Quaife probably will have no idea what you are talking about.

I thought Tom worked for Quaife.

On my car traction control is still running overtime, and is behaving (straight line) about the same as my previous clutch LSD. I'll take it that the ATB unit is biasing the torque quicker than the traction control reacts, so they are not working contradictive.
but i guess when you have the stock eaton you might not get slip at all anymore.

I hear you I'm just wanting someone to get ahold of the right people so we can get some feedback as I'm not able to call overseas. If no one finds out anything I may do the email since avos posted the email address.

As far as I can tell, no-one has yet asked anything or been refused any answers so you would appear to be rather out of order!
Just a thought but you're driving a car which was designed and made here so a bit odd not to be willing to buy parts from here.

The part number of the original (unaltered) LSD is probably useless, considering that none of us know what Tom did to it.
The best info in this case is a phone number to speak to the man.

If this guy Tom has modified the quaife to work, then he adds value to the process by figuring this out.
My questions to Tom is/are:
How much does he sell the 'modified?' quaife unit for?
Whats involved in swapping it into our pumpkin?
I'd also like to know that the mods are 'safe' as far as the diff longevity etc
Has anyone got an STR pumpkin around as a guinea pig? I'm familiar with Ford IRS 8.8's, but I know almost nothing about our stype diff.

My only concern: will the modified Quaife unit also work in the newer axle housing. By that I mean the axle housings that were replaced because of the known "Rear End Wine".
I'm sure that there's a lot of people out there who have the newer axle housings and don't even know it. Especially if they bought their cars used.

I emailed Tom yesterday and got a response today.
The unit we use fits into all S-Type 4.2's including S-Type R's. This is a unit that we have developed in house using a Quaife TAB Center. It's not a straight fit and we do have to do some machining etc to make it work. But we would be more than happy to supply you a diff with the Quaife unit fitted and fit this to your vehicle if required.
Regards
Tom
By this I'm gathering since he is saying that they supply the whole diff that maybe the diff housing has to modified also. With that I'm gonna have to wait since I cant even imagine what the cost would be to ship a diff across the pond. Maybe once I dig deeper into my engineering degree I'll build myself one for a project.
