heres the deal Im 16 and I bought what I thought was going to be a good daily driver for my self. A93 5.0 5spd hatch I didnt know it had a spool rear so I took the whole thing out and then stuck in a posi unit rear. The first rear had 4.10 this has 3.73 My goal is to rebuild the first one with like a 8.8 inch locker but for now I got this one. It is winning like a baby its louder than the flows the rear end fluid is new and full what could be up. The gears are good too just about new only 5 miles on em.

 

Sounds like the gears aren`t shimmed properly.
