I have some tips that are very useful.
The 2mm crush tube between the front axle bearings are too thin. This will cause the bearings to feel notchy. Not at first but later. Put a 0.2mm shim next to it inside to prevent this from happening.
In most cases you will run the 4mm trailing insert. Glue it stuck with super glue. This prevents slop and floppy front wheels. They are rather cheep so a couple of extras in the spare box does not matter that much if you want to try other trailing inserts.
Buy 2 of the longest ballstuds and replace the ballstuds on the rear hubs and use a nut on the other side to secure them more firmly. Even though you use loctite it can loosen and if you tighten the ballstud too hard it will deform its counter plastic part on the balls side in the hub.
