During assembly, there may be some differential movement in the bulkhead. In
particular, DO NOT check mesh or diff movement without installing suspension
holders and securing bulkhead to the chassis. All parts have specifically
designed tolerances, and only when the car is fully assembled will it have the
proper amount of play where necessary. Check for free movement of all
rotational driveline components once the driveline and suspension are
completely assembled, as well as non-binding operation of the suspension
components.

TIP To prevent dust apply one of the included stickers on the rear part of the chassis to cover the center balancing hole.
In case you use more droop than 104-105mm then by certain set-up configurations of the car the front upper arm may hit the servo saver. This has no influence on the handling of the car however you may want to modify the bottom of the front upper arm to avoid it hitting the servo saver.
