my question is how can i make my stock 10 bolt rear end on my 94 z28 m6 Camaro stronger? Can i swap in 31 spline axles? put a girdle on it? Different posi unit? Any suggestions and where i can get these items is greatly appreciated...thanks!

 

Yes, all of those things, are great ideas for making it stronger..aftermarket wheel studs probably wouldn't hurt either. Also get a part called a "Crush Collar" when u get a rebuild kit.
