I dont think i will have a problem with my axle will i? i have an A4 and i am stock now, and i dont plan on adding any more than 30-40 rwhp, so my 10 bolt should last? And what are some tips to make sure it lasts?

 

Tore out my 3.55 gears and posi on the stock rear end... Now I got a 2 series carrier with 2.73s in the rear from and Auto Z28. I plan on getting 3.73s soon.... anyone have any feedback as to whether or not to keep the 2 series posi and just do 2 series 3.73, or to get a 3 series posi and put in 3 series gears? I've heard the 3 series is stronger? Any help?
