The weak points are the spider gears. The R160 has 2 side gears, and 2 spider gears. If we had 4 spider gears, that would have been a different story. If you ever taken apart the rear diff, you'll know what I mean. Those spider gears are tiny. I've broke my fair share. I weld them up and I have a lot more fun doing donuts and such.
After putting in a good LSD, if it holds up, your pinion/ring gear are next to go out. If not that, then it'll be your little R160 axles. Overtime with and LSD you do look at bearing wear on the pinion gear if the LSD has a strong initial bite/lockup.
