The XRAY 353194 XB8 Graphite Rear Lower Arm Plate set fits vintage XB series cars and helps refine rear-end behaviour for better lap consistency. These plates are a straightforward upgrade to modernise handling on older XB models.
Engineered from 2.0mm CNC-machined graphite, the plates deliver a reliable mix of stiffness and low mass. That combination keeps the rear end stable while allowing predictable weight transfer through corners.
Installation takes only a few screws, so you can change setup between sessions without hassle. Adding or removing the plates is an effective method to fine tune rear arm flex and improve traction across different track surfaces.
