The 3Racing Rear Axle Up & Down Offset Spacer is a focused tuning component for Tamiya F103RM drivers. It lets you experiment with rear axle height to influence corner entry, rotation and exit behaviour on club tracks and race days.
Using this spacer you can alter rear traction and how the car transfers load under braking and acceleration. Small, repeatable adjustments help when dialling in a setup for specific tyres and grip levels.
Designed for a direct fit to the Tamiya F103RM chassis, the 3Racing spacer fits without chassis modification. That makes it quick to install and swap as you try different configurations between runs.
