would it be better if i did the g80 mod to the locker so it stayed engaged at higher speeds soo it does lock,unlock,lock,unlock in snow when accelrating..
You don't want that. That can be hard to control and too much gas at the wrong time and the rear end will pass you up. That's precisely why they are designed to disengage at around 20 mph, safety.
Has anyone changed the gear lube and used a Limited Slip Additive in it? Limited slip additives can damage a G80 locker.
Like anything, the G80 can be abused and neglected and blamed for things that are not its fault.
