Firm Up the Rear with XRAY 353116 XB9 Hard Composite Arm

The XRAY 353116 XB9 Hard Composite Rear Suspension Arm is aimed at racers who need steady rear geometry under thermal stress. The specialist composite lowers flex and maintains handling consistency during hot running conditions.

Material Choice for Thermal Stability

A specially formulated hard blend gives the arm resistance to heat-induced deformation, so chassis balance stays more consistent. Note that the increased stiffness may transmit more force on severe impacts compared to softer arms.

Extended Reach for Consistent Lines

The longer arm profile helps the rear track more predictably, aiding drivers who want improved line holding and stable exits from corners.

How should I tune my setup after fitting the hard composite arm?

Expect the rear to feel firmer. Common adjustments include softer damping, slight spring rate reductions or small toe and camber tweaks to regain mechanical grip and to balance the chassis with the stiffer rear.

Will this arm improve lap times on fast, hot tracks?

On circuits where tyre and track temperatures rise, the reduced flex helps preserve handling consistency which can lead to improved driver confidence and potentially faster laps. Results depend on the whole setup and driving style.

Is this compatible with non-XRAY suspension parts?

The arm is produced for the XB9 geometry. Some third party parts may be compatible, but verify dimensions and fitment before fitting mixed components to avoid alignment or clearance issues.
