XRay Composite Rear Brace Holder With Two Assembly Positions

Composite rear brace holder featuring two alternative assembly positions to ensure correct fitment on both XB8 and XB8E chassis configurations. The dual-position design allows proper alignment of the rear brace depending on the chassis layout, without affecting handling characteristics.

Manufactured from durable composite material to provide consistent strength and reliable support for the rear chassis brace.

Fits: XB8’26, XB8E’26

353337 XB8 Alu Rear Extra Lower Susp.Holder - Semi-Split Bulkhead – Front

The C-suspension holder features lower mounting position and updated geometry to increase traction and improve stability.

All front and rear suspension holders offer a wide range of setup adjustments using the included eccentric bushings. Each aluminum suspension holder features Integrated Suspension Settings™ (I.S.S.), allowing quick and precise suspension geometry changes. With eccentric bushings inserted into the holders – together with additional suspension shims – the suspension geometry can be easily tuned for any track condition.

All holders are CNC-machined from Premium Swiss 7075 T6 aluminum and finished with a black anodized surface for maximum durability.

Fits: XB8’23 onwards, XB8E’23 onwards

353527 XB8 Composite Rear Wing Holder - Extended Support Area

Composite rear wing holder featuring an extended support area at the wing mounting interface. The enlarged contact surface provides a stronger and more secure connection between the wing and the mount, helping the wing withstand impacts and reducing the risk of deformation or loosening during crashes.

The wider mounting footprint improves wing stability under high load and at high speeds, ensuring consistent downforce and predictable handling. The one-piece composite design maintains a lightweight construction with controlled flex, allowing effective impact absorption without compromising rigidity.

Manufactured from durable composite material for long service life and reliable performance in demanding racing conditions.

Fits: XB8’23 onwards, XB8E’23 onwards
