Save your money and get an air or electric lokka.
IMO you'll be disappointed in having auto lockka
in front, as you can't turn it off if for eg trying to catch up with the convoy.
You only use lockkas sparingly, maybe on the back but its N/R as great LSD
Your steering will be compomised as well, I would never put one in the front.
but some people swear by them, bet they'd swear at them if they fitted an air lockka.
Go for a drive with an experienced person with a lockka and see how many times and when they use it
Then follow doing same track, It may surprise you M2Cw
