Team Brood Racing Aluminum Brushless Rotor Shim Kit

Dial in your motor like our Pro Build Blueprinting Service with the Team Brood Aluminum Motor Shim Kit — the precision tuning solution for serious racers running modern brushless motors. 

Inside the kit, you’ll find CNC-machined aluminum shims in nine exact sizes, from .010" up to .050" in .005" increments. That range gives you ultra-precise control over rotor positioning — a critical factor for timing accuracy, magnetic centering, and overall motor smoothness.

Aluminum is lightweight, corrosion-resistant, non-magnetic, and far harder than plastic, meaning:

• No deformation over time
• No interference with rotor/stator magnetic balance
• No changes in spacing that affect timing alignment

Just consistent, repeatable results — run after run.

Everything comes packed in a compact, hard folding container with individually labeled compartments, so your shims stay organized and protected whether you’re wrenching at home or traveling to a big race. No mixing, no lost pieces, no frustration.

With 108 total shims covering the full thickness range, you’re fully equipped to fine-tune spacing on nearly any popular brushless race motor. 

Designed for standard 1/8" motor shafts (.125" / 3.175mm).
