Yokomo Z4-300FS Sus_spacer F/1.0m (Non-Chamf) for YZ-4 front suspension spacer  [Z4-300FS]

Front suspension spacer for YZ-4

This RC-scale spacer fits between the YZ-4 front suspension mount and the main chassis to alter the roll center. It is a purpose-built part that changes the suspension geometry in a predictable way without modifying the mount or chassis holes.

The component is described as Non-Chamf and marked 1.0m in the product name. It is intended to be inserted under the front suspension mount to raise or lower the effective pivot point, affecting body roll and initial turn-in behaviour on the track.

Installation is straightforward: the spacer is positioned between the existing front suspension mount and the chassis and secured with the original fasteners. After installation, recheck wheel alignment and suspension movement to confirm clearances and symmetry.

Tuning notes: small changes to roll center with spacers can shift weight transfer and front bite. Use this spacer as a discrete adjustment step while keeping other suspension settings constant to evaluate its effect.
