3Racing 3RAC-WFS820/RE Precision Shim Upgrade

This set of six red anodised aluminium shims is intended for racers who demand repeatable shock tower geometry changes. The 3Racing shims allow precise adjustment of shock mounting position to tune roll centre and damper leverage for consistent lap to lap performance.

Racing-Oriented Tuning Advantages

Using solid aluminium shims reduces variability compared with softer spacer materials, yielding predictable handling when cornering and under braking. The lightweight profile preserves vehicle balance while enabling measurable setup steps for fine tuning.

Installation and Setup Recommendations

Fit shims on either front or rear towers to alter pivot points and experiment with camber gain and roll speed. Combine incremental shim changes with adjusted spring rates and damping to isolate effects and achieve optimal setup for track conditions.

What is the best approach to test shim changes at a meeting?

Change one parameter at a time. Fit a single shim increment, run laps to record differences, then adjust damping or springs if required. Trackside notes help reproduce successful settings.

How do these shims interact with antiroll bar tuning?

Shims change roll centre and can alter load distribution across the antiroll bar. When adjusting bars, reassess shim setup since combined changes affect roll stiffness and balance.

Any tips for verifying consistent installation?

Use a small set of calibrated shims and record exact stack combinations. Verify screw engagement and tower parallelism after installation to ensure geometry matches intended setup.
