I've gotten completely frustrated with trying to get my new Quaife LSD installed locally -- TPC wants way too much money, and the local dealer is extraordinarily reluctant to do it (they had a bad experience with a 911 diff swap, but....)
So, I'm going to just install it myself. The current plan is to do it this Sunday, 6 May, starting about 9 am.
If anyone is interested in coming over to watch, help or just hang out for a while, send me a PM and I'll send you my contact info. I'm in Silver Spring, MD, near where Randolph Rd and Georgia Ave cross. All folks on this board are welcome.
Wish me luck.
LSD - Limited Slip Differential
A limited slip differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.
The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely– the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use however, such as driving off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

Good luck, and which local dealer is reluctant to do the install?

you'll be starting that at the same time the zone 2 PCA car show starts on Sunday! You should do it at Deutsch Marque and start a crowd....
PCA - Porsche Club Of America
The Porsche Club of America - http://www.pca.org
CaymanClub.Net members who are also PCA members should request access to the PCA Member only forum by filling in their PCA Member ID# into their profile and then requesting a group membership addition, both of which can be done in the User Control Panel (User CP)
Have you checked out the other Porsche independent shops around. I dont have the "Porsche Patter" newsletter (must of trashed it) but there were at least three local shops working on Porsches. You might want to check it out. TPC seems only interested in 911s.

The car show sounds very interesting, and it would certainly be an experience to do it at the show, but the organizers probably wouldn't be too thrilled by that, and all my tools are here. Besides, if for some reason I can't get it done on Sunday, I'd rather have the car sit in my garage than in a field or on the back of a flatbed.
chows4us --
I wouldn't necessarily say I have the "expertise" for this, because I've never done a diff swap on a Porsche before. However, I have rebuilt several engines (including a 911 motor) and lots of various other car/truck components, I have a <Spicoli voice> gnarly set of tools </Spicoli voice> (including a Bridgeport milling machine) and I've never let fear of the unknown stop me before.
I have read K-Man S' install article, and all the relevant Porsche workshop manual chapters. This isn't rocket science, and all I really need to do is make sure the ring gear is in the same relative position when I'm done -- there are only three surfaces involved: left bearing shoulder, right bearing shoulder and ring gear mounting face. Besides, with any luck, it'll all just drop in, like advertised.
I have also ordered an assortment of shim stock, so I can cut shims as needed. I have also ordered spare seals, just in case.
And finally, if I just can't get it to fit, I'll put the old diff back in and take it to my appointment in two weeks.
Good luck. I'm pretty tempted to do the same. My dealer said the same thing. After complaining a bit, they decided that they wouldn't do that because it would void part of my warranty.

I'm thinking you should all drive to KC for an LSD Party - wouldn't Timothy Leary be proud? - at Imagine Auto and have them do the install. You could take more pics and fill in any holes in my article where I was unable to snap pics due to being on conference calls. Bummer.
