About The MBX8R


Suspension

The suspension system integrates updated "C" and "D" blocks with refined inserts for enhanced performance. Durable, impact-resistant material is employed to craft longer box-shaped arms, ensuring increased longevity. Notably, the rear uprights have been upgraded, utilizing carbon fiber-reinforced polymers (CFRP) to facilitate roll center adjustments. These enhancements contribute to a more tunable and advanced suspension system.

Chassis and Drivetrain

The chassis underwent an overhaul to align with the updated suspension geometry. Significantly, the drivetrain experienced substantial enhancements in the differential system. High Traction Differentials (HTD) are now employed to deliver heightened acceleration, extended runtimes, and more dependable handling. The differential upgrades include a larger volume differential cup, promoting consistency and facilitating precise timing through rhythm sections, thereby enhancing traction. Additionally, at the rear of the chassis, a lightweight, IFMAR-compliant, high downforce wing is incorporated to further refine jumping performance.

Clutch

The provided 4-shoe clutch is a sophisticated component that offers ease of maintenance and tuning. Crafted from aluminum, this 34mm clutch is equipped with adjustable spring tension, allowing precise customization of engagement to align with the racer's engine, track conditions, and individual preferences. The clutch is coupled with a 13T clutch bell to deliver optimal out-of-the-box performance.
