About the MR-04 EVO2 Mini-Z Chassis Set
Advanced Suspension Design
The MR-04 EVO2 introduces a redesigned front suspension system that significantly improves handling precision and consistency. Its integrated kingpin knuckle reduces play and enhances camber stability, ensuring that the chassis maintains optimal tire contact through every corner. A revised caster and trail geometry delivers more linear steering response, allowing drivers to predict and control movements with greater accuracy. Combined with smoother suspension operation and lower rotational resistance from updated ball bearings, this design helps the EVO2 stay composed at high speeds while offering racers a confident and responsive driving feel.
High-Precision Gyro & RC Unit
A major leap forward is the inclusion of the upgraded gyro unit with a dedicated CPU for ultra-fast response and accuracy. This next-generation system eliminates the performance issues of older gyros, delivering unmatched stability and sharper cornering. Additionally, an updated MR-04 EVO2 RC Unit enables motor RPM control for precise tuning while maintaining compliance with 2025 Mini-Z Cup regulations.
Optimized Chassis & Drive System
The MR-04 EVO2 achieves a lower center of gravity by mounting the batteries closer to the chassis base, resulting in greater stability and smoother cornering at higher speeds. This design works in harmony with the sensored brushless motor to deliver efficient power and precise throttle response. A ball differential is included as standard, providing improved traction and balanced handling by optimizing rotational differences between the rear wheels during turns. Together, these refinements ensure the EVO2 performs with both speed and control, making it a formidable choice for competitive racing.
