I was on google for 2 seconds and found it lol

Q: What is posi?

A: Posi is a rear differential unit that keeps power applied to both wheels as consistently as possible, as opposed to just one wheel in an "open" rear. In general, a posi unit will "lock up" both wheels under power but with reduced power (in a corner) the axles are allowed to rotate independently and thus make going around corners possible without taking all the rubber off your tires. Posi is short for posi-traction, or "positive traction".

And that's that...easy as pie.

That explanation is a bit simplistic. A major function of "posi" (which is actually a Chevy moniker...Ford had Tru-Trac and other comapnies made up their own dumbass names) is to sense a difference in wheel speed on either side and apply most of the engine's torque to the wheel with the most traction. It really depends on the differential. I run a Torson T-2R differential which is entirely gear driven unlike...say...Auburn which uses clutches. Very different torque biasing. Then again, in the domestic world, the term "posi" is pretty much slapped on any limited slip differential. Really anything that's not a ratchet type or locker is called "posi" regardless of who makes it or how it gets the job done.

So what does it mean when someone "lays down a posi strip"

[CD5Passion]

the tire with the most traction leaves a shit load of rubber?

[ChrisCantSkate]

both tires spin durring a burnout...
