I know the N/A drivetrain is weak, but how weak? I've ran welded differential in all of my previous cars, up until my current TII. I have an old welded n/a diff laying around, I know the flange doesn't match up, but that aside...Will the diff/axles hold up? I'm not making gobs of power. its just a streetported s4 with s5 turbo

 

well... its the same thing that breaks on both the na and t2 diff. just keep the tires think and your good to go


home bacon.
