Unless you in an area with mud/snow where traction can be iffy or are Drag racing where traction is also an important issue a Posi is pretty much just braggin’ rights. On most regularly driven street cars the Posi is really only exercised far less than 1% of the time.

I’m not saying bragging rights are a bad thing……. lets face it would you admit your mondo motor 4 Speed Hot Rod has a peg leg rear end or worse prove it by leaving just one black tire mark.

That being said 3 of the 5 cars I currently have registered and insured have Posi’s in them (the other 2 are the wife’s cars )
