This special version features a high-quality chrome-plated body of the Sauber C9. Originally developed as a Mercedes-Benz works machine, this car became a legend in the World Sports Prototype Championship. The premium finish captures the iconic silver arrows aesthetic, providing a scale look that stands out on any Mini-Z circuit or display shelf.

While retaining the best aspects of the previous generation, the MR-04 delivers significant performance gains through a lower centre of gravity. This redesign makes the car easier to control, providing a more stable platform for both competitive racers and beginners. The improved balance ensures smoother weight transfer and more predictable handling during technical indoor racing.

The included Syncro KT-531P transmitter features a realistic steering wheel design and a pistol-grip throttle. You can easily adjust the neutral positions, steering angle, and dual rates using the integrated trims. For those learning the ropes, the default training mode reduces the vehicle speed, allowing new drivers to build their skills safely and gradually.

The newly adopted Suspension Parts 2.0 system brings a revised caster angle to the MR-04 platform. This engineering update balances agility with high-speed stability, ensuring the car remains composed during fast straights and aggressive lane changes. It allows you to push the Sauber C9 to its limits without sacrificing the precise tracking required for carpet racing.

Powered by four AAA batteries, the MR-04 mounts its power source lower than the MR-03. This further drops the centre of gravity of the entire chassis, delivering improved cornering stability and straight-line handling. Whether using alkaline or NiMH cells, the weight is positioned to maximise traction and minimise chassis roll during high-speed manoeuvres.

The front suspension is designed to dynamically align the camber angle with the movement of the upper arm. This ensures the tyres maintain optimal contact patches with the track surface during heavy cornering. Combined with improved steering response from the revised caster, this system provides the front-end bite needed to navigate tight hairpins with total precision.

The rear suspension uses a coil spring Shock to cushion shocks from the road surface and improve overall driving stability. This setup ensures the rear pod remains settled over small bumps, providing a smoother ride on various indoor surfaces. For those looking for even more precision, the system can be upgraded to an optional oil-filled shock absorber.

The rear suspension utilises a flexible T-bar plate to hold the entire rear pod, including the motor and rear axle. This produces a natural suspension effect that improves mechanical grip. This critical tuning part can be swapped for optional FRP or carbon fibre versions, allowing you to customise the chassis flex to match your specific track conditions.

Every axle is equipped with low rotational resistance ball bearings as standard. By using the same size bearings for both the front and rear, Kyosho has improved spare parts efficiency while ensuring a smooth, friction-free drivetrain. These high-quality bearings allow the RWD system to spin freely, maximising the efficiency of your AAA batteries and motor.
