Technical Note on 3RACING Lower Spacers

The 3RACING SAK-C167A M3 x 8 x 1.5 Lower Suspension Spacer is a precision shim intended for controlled modification of suspension pivot stacks on Cero platforms. Tuners use this part to alter roll centre and leverage ratios in measured increments.

Performance Application and Tuning Intent

Positioning the M3 x 8 x 1.5 spacer within the lower mount stack shifts suspension geometry without changing arm lengths. This allows setup engineers to tune transient response and mid-corner balance while maintaining baseline damping and spring rates.

Installation and Setup Procedure

Fitment is achieved with the existing M3 fastener stack. Install the spacer, verify free articulation through the full travel, and log handling changes. Use incremental tests to validate lap time or driver input improvements and avoid overcompensation.

What is the measured effect on roll centre?

Adding the SAK-C167A spacer raises or lowers the effective lower mount height relative to the chassis datum, producing predictable changes to lateral roll centre depending on placement and stack height.

Should I adjust damping after fitting the spacer?

Minor damping tweaks may be beneficial to complement geometry changes. Adjust rebound and compression in small steps and retest to keep dynamic behaviour in harmony with the new geometry.

Are there recommended measurement checks?

Measure static ride height, camber at ride height, and confirm no binding across suspension travel. Log lap times or driver feedback for each spacer increment to ensure objective setup decisions.
