Works'91 TeamSpec Graphite Spacer 2.0mm for Upper Deck - YZ-003SG by Yokomo  [YZ-003SG]

Upper-deck graphite shim

The YZ-003SG spacer is a 2.0mm graphite shim that locates between the rear bulk and the upper deck on Works'91 TeamSpec cars, focusing stiffness locally to influence rear behaviour and stability.

Fitting is straightforward: place the shim between the rear bulk and the deck stack and secure it with the existing deck screws so the chassis layout is unchanged. Because this adjusts the local rigidity rather than altering geometry, expect differences in traction and responsiveness rather than ride height or travel range.

This spacer is useful for subtle, reversible tuning adjustments—reduce rear flex on tacky tracks or make the rear respond crisper through short-radius sections.
