The YZ-003P aluminum post is a scale replacement part made to support the upper deck at the centerline of Works'91 TeamSpec chassis. It acts as a structural mount point that keeps the top deck spaced and aligned with the main chassis rails.
Tuning role and handling impact: fitted at the chassis center, this post alters how load is transferred across the top deck, changing mid-section stiffness and the balance between front and rear responses during cornering. Use it when making gradual setup changes to evaluate deck stiffness effects on handling.
Installation tips: install using the central upper deck mounting positions on compatible chassis models, verify hole alignment before final tightening, and check thread engagement and clearance around suspension links after fitting.
Suitable for YZ-W91TS and YZ-W91 chassis, Works'91 TeamSpec.
