Well... I pulled the trigger on a LSD :D
 

I broke down and bought a Quaife TBD for my car after driving a reasonably modified Cayman S last weekend at an autocross. The Cayman with the Quaife was extremely willing to be driven at the edge with what felt like very controllable oversteer and a tremendous amount of grip. I should receive it sometime next week.

Will you be installing it yourself or farm it out?

Cost? Car?

I'm jealous! :)

You are brave soul. LSD installs look quite involved.

At the time, the LSD cost ~$1400 and the install cost $550 or so.

2002 Boxster S

No feedback or was it done on another post?

Nobody seemed interested until yesterday so I hadn't provided feedback. It is by far the best modification I have made so far (compared to springs, sway bars, engine stuff, etc) as the rear end has a new level of grip. I autocross quite frequently and it has made a huge difference. I now have a tremendous amount of grip when accelerating out of corners or taking "long" curves where I would get the rear to lose traction before the TBD.

I don't push the limits of traction on the street (other than an agressive launch here and there) but I can say that I don't notice it when driving on the street. :)

Any specific questions?

:cheers:

The install was about $550? Who did the work? I'm not sure about the Boxster, but LSD installs require a lot of labor and work on other cars. The transaxle has to be removed and completely disassembled so $550 seems low.

I did a lot of LSD in the 60's, and I can tell you that $550 is a lot of money for the stuff.

If you do some searching on some of the Cayman sites you will find that this is in line with their estimates as well. The TBD was installed with the transmission still in the car but yes, the transaxle had to be removed and disassembled.

I don't understand. You said the transmission stayed in the car, but the transaxle had to be removed and disassembled? A transaxle is a transmission and a differential as one unit.

The transmission housing stayed in the car but the half-shafts and the differential were disassembled from the transmission housing. The differential was replaced with the new TBD and everything was reassembled. My apologies if I used the wrong terminology.

There is a write-up over at www.planet-9.com which gives you an idea of how the process worked if you are interested. I thought about doing it myself as a friend of mine did with his Cayman; however, I didn't want to mess around with trying to get it shimmed properly and I thought the install price was reasonable.

Ok I see. Thanks for the explanation. I'll check out that link.
