Ideas: Pay attention to the differential and suspension arm shimming:
The diff will should be adjusted from the inventory #81015 gearbox. Really helpful to start out with one skinny (0.1mm, the thinnest accessible) on both sides.
Professional Tip: To positive tune the suspension arm shimming on the internal hinge pin, use 0.9 or 1.0 caster adjustment shims from the #81446 RC8B3.2 Shim Set, and you’ll trim off the pull-tab for floor clearance.
