UPDATE #2: Talked to Brett Again
Since some of you are still interested in the Quaife LSD versus Brett's new Salisbury type unit, I decided to call Brett again and discuss the requirements of getting the Quaife. Essentially, nothing has changed from what was posted on the BMWZ8.us board this past summer.
Brett's main issue is that it took two and a half years for him to sell the lot of 30 Quaifes that he originally ordered, and he's not going to shell out the money to order another batch for a part that only fits a small production vehicle like the Z8. Can you blame him? This is blessing and burden of such an exclusive vehicle.
So, if you want a Koala Quaife, here's the process:
1. There are no Quaifes left in inventory. So, a batch would need to be produced.
2. The smallest lot that Quaife will produce is ten, and Brett would have to pay for the lot in advance. As such, Brett would require ten customers to pay $3,000 in advance before ordering the lot.
3. After the tenth order is placed, it would take six months for Brett to receive the Quaife LSD.
4. As the fitment requires modification to the carrier, there is additional machining time that Brett needs to complete the entire final drive assembly with the Quaife. Currently, he only has two Z8 cores, and could only build two final drives at a time. So, there could be a several month wait for all ten customers beyond the initial six month production.
So, unless there are ten of you that are willing to put down $3,000 and wait at least seven months, it looks like the days of the Koala made Quaife LSD are over. While, Brett would be pleased to go through the process above, he doubts that there are ten people that step up to the bar.
This is why he has designed/built the new Salisbury type diff, which has locally sourced parts and can be produced in smaller batches. Brett admits that the wear of the friction surfaces is a disadvantage over the Quaife, but he's quick to point out all the standard BMW LSDs (and the one that would have been on the Z8) are of similar design with a 25% lockup. His unit will be continuously variable with a 40% lockup. Brett estimates that wear on the friction surfaces will reduce the lockup on his unit to 25% in 100k miles. He also estimates that friction surfaces can be replaced by many shops across the US for less than $1,000. Again, this solution will be $4,250 with the 3.64 gears.
Drexler, outside of Passau, Germany, also offers a Salisbury type LSD for the Z8. Z8Doc got a quote from the for 4,470 Euros (plus delivery) for the LSD, final drive, and 3.64 gears. Their portfolio of customers is just as stout as Quaife. I have no information on production time or delivery.
So, in my opinion Brett's new LSD may be the best alternative. Yes, the Quaife is probably a better unit, but it's lack availability simply removes it from consideration. For my driving patterns, and probably 95% of you, a clutch based solution will provide more than ample results as it will provide vastly improved performance over the stock open diff. Don't forget that if BMW had included the LSD as advertised, it would have been a clutch style, and probably none of us would even know about the Quaife (GM excluded).
If there are nine of you (I'm #1) that are willing to put down the money and wait on Quaife, great. Let's get organized fast, but if all you're going to do is post "I'm interested" and not follow up, don't bother. There's no need to waste a bunch of time and effort unless we have ten serious people.

There is no list for the Quaife
Unless you've sent $3k to Brett, you're not on a list for the Quaife. As of this morning's conversation, he has taken ZERO deposits for the Quaife, but there are four or five people in line for his new Salisbury type diff. My guess is that you're on that list. I'd give Brett a call and check. I believe there are several of you under the assumption that you're on a list for the Quaife.
If you and others are serious about the Quaife, we need to get ten $3,000 deposits to Brett ASAP. Macfly, can you add a voting sticky to the Quaife group buy discussion on your board to help us measure the actual demand for the Quaife and the number of people that will put deposits down today?

yes, certainly can, please let me know what are
the options that you guys would want to vote on:
* I want the Quaife, and am happy to send $3K to Brett and wait for the best unit.
* I want the Sailsbury type unit that Brett is selling now.
* I want the Drexler LSD from Germany
I was waiting the Z8Doc to send me over the outcome of his investigations into the various units available, as I believe he may have a couple of options to throw into the pot as well. Let me know, and I'll get it up asap.
The chat is here;

My info on the Drexler is from Z8Doc
He and I talked a good bit on the subject this weekend after our day at the TMSR. As noted in my post above, he got a quote for 4,470 Euros for the Drexler LSD rear end (includes clutch LSD, carrier, and 3.64s).
If you do some digging, it does look like some people claim they carry the Quaife for the Z8, but no one that I talked to has any in stock. Even if you can find the diff, the carrier requires modification, and Brett's the only one in the US has attempted to do this on even a limited production basis.
From Z8Doc's research and mine, Brett and Drexler seem to be the only people producing the complete final drive for the Z8.

Re: There is no list for the Quaife
I rememeber him discussing the Salisbury but was under the (mis)understanding that as soon as he had 10 buyers, he would make the call for the $3000 deposit, then the wait.
I would prefer the quaife and am willing to send a deposit now if we can round up the 9 others willing to do so.
If that can happen I guess I would settle for a Salisbury.

Re: Drexler Info
I hope this goes through, as Roadfly has banned me for not paying my dues.
A few misconceptions.
The current wait list for Quaife is at 5, but we need 15 (not 10 as suggested in this thread).
Deposit is not $3000, it's $2000, balance due 4-5 weeks before delivery to you.
Drexler unit is ~$4040 with LSD and 3.64 gears. Don't forget international shipping, via UPS (which is Drexler's shipper of choice) at close to $400 for a 100lb package. And core?
Our clutch based LSD is ready to ship, allowing for current production delays of 2-3 weeks.
The clutch LSD (Salisbury style) does wear. We set it at about 40%, and in about ONE HUNDRED AND FIFTY THOUSAND MILES, it MIGHT need to be freshened up, at a current cost of $500. The Quaife won't need this refresh, but.....
Hope this helps. Call me if you have questions. 440 564 7574
