Does the Boxster have LSD?

[deliriousga]

I have not seen it in the manuals, so does anybody know if the Boxster has a limited slip differential (LSD)? If so, is it standard or an option?

TIA!

No it does not and its one of the things that would really improve the car I think.

Drexler makes one (send them a mail a few days ago, no answer yet) and Qualife (not sure about spelling). Send them mails ages ago but never got a reply.

Thanks for the info.

The early Boxes had a traction control option "to maintain maximum traction during acceleration", which included "an automatic brake differential (ABD) and an anti-slip regulation (ASR) to minimize tire slippage."
The ASR activated at engine start-up, but could be turned off, leaving the ABD in operation. "In this mode, the Boxster behaves like a vehicle with conventional limited slip differential", although it functioned in this mode only up to about 62 mph.
All this from the Boxster introduction book published in '96.
I supposed this has all morphed into the PASM on the newer cars.

That marketing jumbo. ABD is nothing like a real mechanical LSD. ABD brakes the spinning wheels and revers torque to the other by that means. True, it will work better than nothing, but a real mechanical LSD with a high locking % will work a lot better.

The Monster Boxster on renntech.org has the Quaife LSD.
