And posi trac and limited slip are technically the same thing, just that posi trac is the GM brand name for their limited slip axles. There are different types of limited slip technology. Clutch pack, viscous, torsen, etc. All of these limit the amount of wheel spin only 1 tire can see on an axle.
These are not to be confused with locking diffs, which physically lock the wheels together keeping them at the same speed equally. There are also different types of locking diff technology.
A limited slip is a much better diff for a street car because they are smooth and give just the right amount of extra traction needed. Locking diffs are used more in off-road trucks and extreme traction situations, but can be uncomfortable and unwieldy on the street.
