These +1mm hubs allow for extra high diff or solid axle position compared to the kit eccentric parts. The extra high position improves rotation.
These beautiful 7075 T6 aluminum adjustable ball-bearing hubs are direct replacement of the standard composite ones included in the kit. The aluminum hubs reduce the friction and make the car to run more free with increased the drivetrain efficiency.
The aluminum hubs are stronger and more reliable with increased life span. Black coated. Set of 2.
• Designed for X4F to improve rotation
• Ball-bearing mounting system
• Super-fine tuning
• Fits X4 & X4F
• Laser-engraved stripes for easy identification

Rear anti-roll bar for ball-bearing roll bar mounting system works with rear suspension arms. The anti-roll bar system is mounted to the rear bulkheads via bearings from outside for extra-smooth movement and for quick & easy changes and adjustment. The roll bar turns in ball-bearings for maximum precision and free movement. Anti-roll bar height is adjustable via a screw... quick & easy.
Anti-roll bar has laser-engraved stripes (corresponding to bar thickness) for easy identification.
Must be used with #303434 Alu Anti-Roll Bar Bushing o2.0mm - 6mm (2)

• Hard composite hub
• For low-medium traction asphalt & very-low carpet tracks
• Generates more mechanical grip
• Improves side traction
• Universal design fits front & rear
• Fits X4 & X4F

Precision-molded Hard composite hub for X4 platform. Hard composite is softer than Graphite material and thus generates more mechanical grip on the car and improves side traction. Recommended for low-medium traction asphalt tracks and very-low grip carpet tracks.
The hubs allow full adjustability of the axle height to adapt the car to every condition.
The aluminum front steering plates and rear ARS plates are easily mounted depending on the hub's location.
The design of the hub is universal with the same part used at all four corners with corresponding extensions.

Machined and molded from thinner premium-grade graphite and softer composite materials. The arms are super lightweight and very compact. Soft arms generate more mechanical grip on the car and improve side traction. Recommended for very low & low traction asphalt and carpet tracks. The softer arms are slightly more fragile.
The unique CFF suspension soft arms are an elegant engineering achievement that look great and perform even better on the track. Using XRAY's own developed manufacturing process, a carbon fiber arm and composite arm are molded together using a fusion process to produce a single CFF suspension arm.
The benefits of the CFF arms are tremendous. The thickness of the inner carbon fiber plate determines the hardness and flex of the arm. The composite around the carbon helps control its flex and rebound, resulting in a very consistent feel from corner to corner.
• Quick, precise & hassle-free roll-center adjustment
• Improves steering when used in front
• Improves rotation when used in rear
• Improves graphite durability in crashes when used in front
• Fits X4 & X4F
