3RACING 3RAC-SW12 Precision 12mm Shim Pack 0.1/0.2/0.3mm  [3RAC-SW12]

Small Shims for Smart Setup Changes

The 3RACING 3RAC-SW12 12mm shim pack gives model racers a simple way to adjust fine tolerances. With three thickness options you can make measured tweaks to alignment and clearance without guesswork.

Improve Suspension and Drivetrain Feel

Use these spacers to reduce unwanted play at pivots, secure bearings or refine gear mesh. The controlled thickness increments let you tune handling and drivetrain smoothness for different track conditions.

Bulk Supply for Practical Tuning

Each thickness comes in a set of 10 pieces, so you can carry spares and apply the shims across multiple areas of the car. The quantity supports iterative setup changes during practice and race days.
