YZ-4 Front Suspension Spacer 1.0m Non-Chamfer - Yokomo Z4-300FS  [Z4-300FS]

YZ-4 front spacer overview

This RC-scale spacer sits between the YZ-4 front suspension mount and the main chassis to modify the roll center. It is a dedicated spacer that alters suspension geometry predictably without drilling or changing existing mount holes.

The part is labelled Non-Chamf and stamped 1.0m in the product title. It fits under the front suspension mount to change the effective pivot height, influencing body roll and initial turn-in response on the circuit.

Fitting is simple: place the spacer between the front suspension mount and chassis and secure using the original fasteners. After fitting, inspect wheel alignment and suspension travel to confirm clearances and symmetry.

Tuning tip: small roll-center shifts from spacers affect weight transfer and front bite. Add this spacer as a single-variable change while keeping other suspension settings constant to evaluate its effect.
