"Funky" is a good word, not the one I use ;)

See now, here's where it gets tough for a guy like me... After spending
mucho time and dollars (mine and customers) with a plethora of different
hardware, I'm somewhat reluctant to give this away freely. That said, on a
street S car, more than 400in/lb rear gets stiff. Ok?

If it's hooked up it increases effective spring rate, that would be true if
it was 12mm. I'm all for max wheel travel in audis.

Many have intimately ;). Teddy, you should join the torsen list. IME
(summarizing a lengthy discourse) that center device isn't 'limited slip,
it's a "no slip" device, which means it's biggest flaw is torque transfer
based on turning radius *or* traction (documented in several papers). That
doesn't always operate in the drivers favor.

25in/lb and 2in length at a time. That gives you a myriad of choices. For
more on what's available for the S cars, try the urs4 site. If you go out on
your own, you will find the rates listed there as great guildlines.
