About the MR-04 Mini-Z

Advanced MR-04 Chassis

The MR-04 chassis represents a major evolution from the MR-03 model, offering enhanced performance and improved handling. With a lower center of gravity and redesigned steering geometry, the MR-04 provides superior cornering stability and smoother straight-line driving. The front knuckles with integrated kingpins reduce scrub, offering sharper and more precise control, while the revised caster angle improves steering response during high-speed maneuvers.

High-Quality Components & Construction

This ReadySet includes a beautifully painted Toyota GR Yaris body finished to display model standards. The chassis is equipped with full ball bearings to minimize rotational resistance and features a geared differential for smooth cornering. The rear suspension incorporates a coil spring damper, and the T-bar rear suspension plate adds flexibility for better road absorption. These high-quality components ensure durability, smooth operation, and excellent driving performance.

User Friendly Electronics

The MR-04 chassis is compatible with an optional gyro unit (KYOMZW711 – sold separately) that enhances driving stability by reducing oversteer and understeer. The gyro sensitivity can be adjusted directly from the chassis for customized handling. The included Syncro KT-531P transmitter provides intuitive control with a steering wheel and pistol-grip throttle for a realistic driving experience. It features adjustable trims for steering and throttle, dual-rate adjustment for steering angle, and a training mode to reduce vehicle speed for beginners. With these user-friendly controls and optional enhancements, drivers of all skill levels can enjoy precise and responsive handling.
