The reason your buddy broke his ring gear is due in part to running a manual tranny. Manual trannys shock the driveline very aggressively. In contrast to this is the automatic transmission which does not shock the driveline as much. I pull consistent 1.7x 60ft times in my car which has the 10-bolt (albeit modified somewhat) and don't have any problems. But, I have an automatic.

Manuals are really really hard on rearends and driveshafts
Autos are softer on rearends and driveshafts
