The Mugen Seiki MBX8R 1/8 Off-Road Competition Nitro Buggy Kit has been developed to provide racers with the leading edge. The MBX8R has many updates over prior models leading to improved stability, rear traction, improved jumping and have a wide tuning range. These updates give racers the adjustments needed for any track condition.
The suspension uses narrow "C" and "D" pivot blocks with revised inserts. Longer box-shaped arms are made from impact resistant material for increased durability. The rear uprights have also been given improvements and use carbon fiber reinforced polymers (CFRP) to adjust roll centers. These improvements allow for a more tunable and more advanced suspension system.
The included 4-shoe clutch is more advanced and can easily be worked on and tuned. This 34mm clutch is made from aluminum and features adjustable spring tension to fine tune the engagement to best suit the racers engine, track conditions and personal preference. The clutch is paired with a 13T clutch bell for out of the box performance.
Chassis and Drivetrain:
The chassis has received key updates to accommodate the revised suspension geometry. The drivetrain has received major updates to the differentials. High traction Differentials (HTD) are used to provide increased acceleration, longer runtimes and more consistent handling. A larger volume differential cup increases consistency allows the racer to easily time rhythm sections and further increase traction. In the rear of the chassis, a lightweight, IFMAR legal, high downforce wing is used for a further improvement to jumping.
