At the end of 2023, the Mini-Z MR-04EVO2 underwent a full model change for the first time in 14 years. Retaining the proven MR-03 layout, major performance gains were realized with a sensor-equipped brushless motor, redesigned front suspension, and lower battery center of gravity. This chassis set includes the high-rigidity “Front Suspension Arm 2.0” as standard, maximizing the MR-04EVO2’s precise handling and stability. The gyro unit is sold separately, allowing greater freedom in setup and tuning. The latest RC unit supports motor RPM control via the I.C.S. Setting Manager, ensuring compliance with 2025 Mini-Z Cup regulations. Power settings can be easily optimized to suit each class. For drivers seeking advanced tuning in a competitive environment, the MR-04EVO2 takes circuit performance to the next level.
While retaining elements of the excellent MR-03 layout, the new MR-04EVO2 chassis achieves significant performance improvements with changes to the front suspension and a lower C of G that work in synergy with a sensored brushless motor. Both narrow and wide tread settings are available by changing the lower and upper plates on the front as well as the steering tie rod. Adjustable wheelbase allows chassis setting according to body type.
While camber angle is optimized during cornering with the swing of the current upper arm design, the front suspension uses the new kingpin-integrated knuckle to further improve camber stability. Geometric revision of caster and trail etc. delivers more linear maneuverability. New spec front springs for the MR-04 with different hardness are available as options.
Front knuckle design features integrated kingpin with optimized clearance with the kingpin ball for smoother operation. Ball bearings have been changed to 3mm internal diameter for lower rotational resistance.
All 7 ball bearings are 3mm internal diameter for lower rotational resistance to minimize friction loss.
Lower mounting of the AAA batteries on the chassis realizes a lower center of gravity compared to the MR-03. In combination with the chassis shape, this improves stability through corners as well as enhancing speed and control.
Ball differential included as standard optimizes the rotational differences between left and right rear wheels when turning. Also provides moderate slip action to improve traction when excessive load is applied. Silver clear anodized finish to aluminum parts creates a formidable style to match performance.
The new unit also supports high-speed communication with various high-end transmitters and receivers to realize unprecedented control response. Achieves transmission speeds of 0.99ms with KO units (ADV mode) and 0.9ms with Futaba units (EVO2 mode). *Previously 2.6ms ~ 3.0ms.
