Are many people using the Gear diff for the b4.1?
I was considering one or am I better off sticking to the standard ball diff?
In tourer everyone uses a Gear diff mainly these days, just wondering if its the same for off road
Just like it TC, it's all about personal preference. Both have their pros and cons. NEITHER has been proven 'faster' or 'better' as a rule, other than for each driver/set up/track conditions.
Mostly ball can be tuned quickly but needs some attention, gear can't be tuned as easily, but once tuned is rather trouble free. Ball is cheaper and easier, and gear requires the purchase of diff fluids.
If you rebuild and maintain often and don't mind maintenance, go ball. If you don't rebuild and maintain often, and hate maintenance, go gear.
