It's interesting to compare the effects of the older and newer style lsds

In my '76 C3 I have an old style symmetric ramp so called 40% lsd, 4 friction plates(2 per side). It is easily felt on low speed right angle turns but becomes transparant at speed, On a lift if you turn 1 wheel the other turns in the same diretion.

In my 993 I have a Porsche Motorsports 40/65 w/ asymmetric ramps 4 friction plates(2 per side) but these are set up w/ less preload that the older ZFs, you don't feel it at low speeds at all, on a lift, turn one wheel and the other goes in the opposite direction just like an open diff. No the plates aren't worn, it is very difficult to hold one wheel while turning the other. At low speeds the low preload allows freerer differential movement but under a load either on accel or braking progressively loads up. Just thing you want to have happen. It is the nuts! (JMO of course)

Spool or auto locker?

Bill's new one sounds like what we all want.

IIRC, it was a spool. Someone else with more knowledge of the K3's will remember.

Spool is about as simple as it gets....
