i have a 92 camaro it has a 305 ... with a slip diff rear ...i have read that a slip diff and a posi are the same ...i problem is why is the posi more dominant to teh right side of the camaro ...and how can i make it so the power is distributed evenly throughout the rear end so both wheel will spin at the same time...

 

Posi is designed to aid in traction, but won't necessarily spin both wheels at the same time. The only way to have constant both axles spinning at the same time is to get something like a detroit locker and install it. All camaros and firebirds tend to squat on that right rear wheel, mainly from engine rotation, etc. If you really want both wheels to spin all the time, get yourself a detroit locker.

 

To get both to spin either have a rear end with a mini spool put in (so it is basically solid) or have a detroit locker put in but u'll still have some right tire spinning a little bit more! Best bet is find a rear end that you can addd a mini spool to

 

Can you ever spin both tires? If not its time for a rebuild or a Zexel.
