I would ask them if the plates are set up for 30-40%, 60%, or 100% locking. That will make a huge difference for you. They should know. If not, you can check before you install it. Hopefully they have it set up exactly as is needed for your car, but more than likely, unless they are installing it, it will likely be a box stock unit from MFactory.Much thanks for this reply guys! About initialize LSD setup - I've bought it in the racing shop, where people with extensive experience with motorsport work (rallies, track racing, etc.). I gave them all the parameters of the car, from power to suspension settings, wheel size and tire type. They just set it to 1 / 1.5 and pre-closure to 40NM.
