Carbon Graphite Rear Roll Plate for BD9 MRTC-BD919/MRTC-BD919S - Yokomo B9-002RPA  [B9-002RPA]

Tuning the BD9 rear roll setup

This carbon graphite rear roll plate is an aftermarket component crafted to influence rear roll stiffness on BD9 touring car chassis. It supplies a purpose-built mounting surface that changes how lateral loads are transferred at the rear, allowing set-up changes without modifying principal suspension geometry.

The plate fits using the vehicle's existing rear pod mounting points and original hardware, so no specialised parts are necessary. Replacing the stock roll plate is a direct swap after rear pod removal and is suited to those familiar with routine rear-end work; it complements shock and tyre adjustments as part of overall setup refinement.

Intended for club and circuit tuning, the plate provides a simple mechanical method to evaluate differences in rear roll behaviour across setups.
