About the MR-04 Mini-Z
Enhanced Chassis Dynamics for Confident Control
The MR-04 chassis builds on the success of the MR-03 with improvements that enhance handling and stability. A lower center of gravity improves cornering and straight-line performance, giving you a more responsive driving experience. The updated front suspension system maintains optimal tire contact, increasing grip and steering accuracy. These refinements make the MR-04 an excellent choice for both casual drivers and competitive racers.
Responsive Steering with Improved Suspension Feel
The MR-04 features updated front knuckles with integrated kingpins that reduce scrub, allowing for sharper and more controlled steering. Enhanced ball bearings minimize rotational resistance, providing smoother and more efficient operation. The rear suspension is equipped with a coil spring damper to absorb track shocks, with the option to upgrade to an oil-filled shock absorber for improved stability on challenging surfaces.
Flexible Tuning Options for Drivers at Every Level
Designed for maximum versatility, the MR-04 supports full ball bearing specifications and is compatible with a variety of optional parts. The geared differential ensures smooth cornering, while the optional gyro unit (KYOMZW711 - sold separately) offers even more precise control. Whether you're a beginner or an experienced racer, the MR-04 provides numerous options for upgrades and performance tuning to match your driving style.
