The facts:
- Automatic Brake Differential (ABD) is an integrated part of PSM and uses the brakes to emulate a limited slip diffential.
- A mechanical LSD is available with the 997 Sports Suspension (which also includes lower ride height and different springs/dampers).

My question is:
What are Pros and the Cons of a mechanical LSD compared to ABD?

On my BoxsterS without PSM (and without LSD) the inner back wheel tends to brake loose when accelerating hard out of slow corners. I understand that both ABD or LSD would prevent such behaviour, right?

I do understand the the Sports suspension brings other benefits besides the LSD, but that is another topic.
