Don't quote me on this, but I believe the 986 has ABD if you got TC or PSM. ABD is standard on 987, so your 06 has it.
It's like a cheap limited slip differential. It works ok. The negative is, by applying brakes to the slipping wheel therefore feeding power to the opposite wheel, it scrubs off some speed. If you're real serious about racing, you'll want a Quaife limited slip or clutch type. For street driving ABD works well enough.
