Works'91 TeamSpec Graphite Upper Deck (2.0mm) - YZ-003GW1 by Yokomo  [YZ-003GW1]

Upper deck fit and installation for Works'91 TeamSpec

The Yokomo YZ-003GW1 is a 2.0mm graphite upper deck engineered for the Works'91 TeamSpec platform. As an aftermarket replacement it focuses on pitching stiffness rather than changing basic chassis geometry. The material and panel thickness increase longitudinal rigidity to alter how the chassis responds to acceleration and braking inputs.

Compatibility is limited to the supported chassis shown below. Fitment is intended as a direct swap for the stock upper deck on those models, offering increased pitch stiffness for drivers adjusting front-to-rear balance without relocating suspension pick-up points.

Install this part when you want a straightforward way to reduce pitch flex across the YZ-W91 series during on-track tuning; it provides crisper weight transfer and more consistent suspension responses without modifying suspension geometry.

Choose the YZ-003GW1 when you need a simple, material-based change to pitching stiffness on the Works'91 TeamSpec chassis; it is useful for drivers refining mid-corner balance and transient responses without altering suspension geometry.
