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.

I had the first generation of the Mini-Z cars when they came with AM radios but the new ones have really evolved, so it’s great that Kyosho continues to make them better. This GR Yaris came with LED lights pre-installed which saved me the trouble of doing it myself. I did have a problem with the transmitter though. I spent time figuring out if the problem was with the car or the radio components but at the end, the transmitter had a badly soldered internal part. I found another vendor selling transmitters really cheap so in the end the car works like it’s supposed to. I have to get a higher end radio system later that I can use with any Mini-Z alongside other R/C’s I’m planning on buying.
