For competitors needing predictable rear end behaviour in hot conditions, the XRAY 353116 XB9 Hard Composite Rear Suspension Arm delivers a firmer platform. The tailored composite reduces unwanted flex and helps preserve suspension geometry during extended runs.
The new hard composite blend was tuned to resist thermal softening, meaning less deformation and steadier handling when track temperatures climb. Keep in mind the trade off: added stiffness can reduce impact absorption.
The arm's longer profile increases stability and helps the rear track truer through corners, benefiting drivers who prioritise line control and consistent lap times.
