For racers and tuners chasing sharper rear-end stability, the XRAY 303190 Graphite Rear Lower Arm Plate is a purposeful upgrade for the suspension. Machined from durable graphite, this plate raises rear assembly stiffness to give steadier handling and more predictable steering when grip levels climb.
The strength of the XRAY 303190 lies in its modular effect on handling. On low-traction runs you can leave the graphite out for a looser rear feel, then bolt the plates in as the track bites more firmly to calm the chassis and improve cornering confidence.
Fitting is simple, needing only four screws to mount the plates to the rear lower arms. The quick fit layout makes mid-event setup swaps straightforward so drivers can refine balance without wasting time.
