Personally I don't see a benefit of Quaife over OEM, but I would go OS Giken Superlock clutch type.

 

We need an order for 10-20 units to get them built for the F-Type. I was thinking about ordering the batch as I did on the V1.0 short-shifters, but I just couldn’t see the eventual demand for them, especially since the base and S have different diff ratios. I might reconsider when I blow up my diff.

 

The benefit of the Torsen is that it relies on positive gearing rather than a slipping clutch to limit slip. Wear and tear will be much less with the Torsen mechanism.

 

can you please give me some link to technical info about the OEM type? I cannot find anything concrete.

Torsen have some problems and if you want to go custom order way, check the OS Giken which is another level. Only disadvantage might me as you say wear and tear, since clutch type diffs require a bit more maintanance. But the diff stays closed even when only one wheel has grip and most importantly the locking is gradual in comparsion to ON/OFF operation of Torsen type. Usually clutch types are noisy, but OS giken have some patent I believe and they are great for street. In short, on other cars equiped with Torsen, the clutch type, especially OS Giken are the no. 1 thing to upgrade and I have never heard of anything else than glory.

 

The OEM LSD (V6S)is a simple friction disc type, which looses its effectiveness fairly quickly with rigorous use.

 

I would drop the e diff for a quaife in a heartbeat. The oem diff is weak, prone to overheating and causing too many issues. I've already had to replace a diff, now I'm getting an e diff fault. I'm so tired of this diff lol.

 

jlsthlm is in the process of swapping his open diff with a mechanical OEM LSD and has offered to send me his open diff. If this happens, I will send it to Quaife to see if they can build us some Torsen units. Don’t know where I’ll store 10 units (minimum first order), but I’ll worry about that later.

 

My only concern is keeping the electronics happy. Because if you unplug the e diff you will get a fault that will lock you out of using the special functions.

 

I'm not able to figure out which differential I have. I read Cambo and your post and don't see it spelled out, Sorry if this is obvious.
2015 V6S Automatic has what of diff?

Thanks

 

Mechanical LSD is what you have.

 

I am in for a Quaife for a V6S, depending on the price. What's the best guess for the price?

 

Based on other makes/models in the same torque range it looks like $1675-$1895. We won’t have a firm number until Quaife gets a look at the OEM diff housing.

 

That price point doesn't scare me away.

 

It shouldn’t. That compares with the OEM open diff at $3900 and the OEM LSD at $2850.
Why the LSD is a thousand bucks less than the open diff is beyond me.

 

This made me a bit worried that I might be looking at the wrong component.

OEM LSD is T2R4000E, no? If so it is 1965 USD at Jaguar Palm Beach,

Or am I looking at the wrong part?

 

If that is the correct part see attached link. You will find their pricing is about the cheapest online.

Hmm the price in the link you shared is actually higher than on the site I linked? 1440 + 525 vs 1536 + 525?

 

You are right, sorry about that.

 

​​​​​​The "E" on the end of that part number means it's an exchange part, right?

 

I am much closer to signing up than ever before, seeing how it isn't ~4K+ I assumed it would cost.

For your next magical trick, can you get better SC cooling parts order going?
