About the MR-04 Mini-Z
Enhanced Chassis for Superior Control
The MR-04 chassis builds on the proven MR-03 design with key improvements for better handling and stability. The lower center of gravity enhances cornering and straight-line performance, providing a more responsive driving feel. An updated front suspension system maintains consistent tire contact, improving grip and steering accuracy. These upgrades make the MR-04 an excellent choice for racers seeking both ease of use and competitive edge.
Precision Steering & Smooth Operation
The MR-04 features updated front knuckles with integrated kingpins that reduce scrub, allowing for sharper and more controlled steering. Improved ball bearings minimize rotational resistance, ensuring smooth and efficient operation during races. The rear suspension includes a coil spring damper to absorb shocks, with the option to upgrade to an oil-filled shock absorber for increased stability on rough tracks.
Customization & Compatibility
This model is designed with versatility in mind, offering full ball bearing specifications and compatibility with a wide range of optional parts. The geared differential ensures smooth cornering, while the optional gyro unit (KYOMZW711 - sold separately) provides even greater control. Whether you're a beginner or an experienced racer, the MR-04 offers numerous possibilities for upgrades and personalized performance tuning.
