The 3RACING 4mm Shim Spacer set is a compact kit for accurate tuning, offering 0.1mm, 0.2mm and 0.3mm shims with ten pieces per size. These thin spacers allow controlled changes to suspension and drivetrain clearances without replacing major components.
Employ the shims to refine camber blocks, correct slight gear mesh issues or adjust hub spacing. Small increments can improve cornering stability and reduce drivetrain noise.
Make one change at a time and test on a short run to confirm effects. The three thickness options make it straightforward to find the required tolerance for smoother operation and improved lap times.
