Full floating 9 inch

[funcars]

I run a full floater with a black diamond diff. It seems very durable to me. No excessive wear of drive plates or axles. I did have to switch to 5x5 wheels though. You can buy new race team surplus NASCAR stuff like brakes, rotors, hats, hubs, drive plates, axles, etc. for cheap. You can do a cambered rear too with the same parts except the housing and axles.
