There’s no need to introduce the Mini-Z anymore—it’s been a legend for over 14 years!

At the end of 2023, the Mini-Z MR-04EVO2 underwent a complete model redesign after 14 years.

Building on the proven MR-03 configuration, the MR-04EVO2 introduced a sensor-equipped brushless motor, a redesigned front suspension, and a lower battery position, which allowed a substantial performance improvement.

Today in 2025, the MR-04EVO2 benefits from a major update with further enhancements. Featuring the 2.0 reinforced front suspension arms first introduced in the RWD series, the updated model now includes the gyro unit widely adopted as standard.

Upgraded to version 2, the gyroscope provides a refined balance between stability and cornering precision, improving both race performance and driving experience. Another major improvement is the new RC unit that enables engine RPM control for precise tuning, essential for drivers while keeping competition fair, as the Mini-Z Cup rules shift from motor KV regulation (rpm per volt) to direct RPM regulation in 2025.

The MR-04EVO2 fully supports this new system and, thanks to the I.C.S. Settings Manager, users can easily configure the motor settings to match the category regulations.

4100KV version, green motor.

• ASC
• AAA batteries for chassis

While retaining elements of the excellent MR-03, the new MR-04EVO2 chassis dramatically improves performance thanks to front suspension modifications and a lower center of gravity that work in synergy with a sensored brushless motor.

Narrow or wide front track settings are available by changing the lower and upper front plates, as well as the steering tie-rod. An adjustable wheelbase allows the chassis to be set to suit the body type.

While the camber angle is optimized in corners thanks to the current design of the upper wishbone, the front suspension uses the new ball joint integrated into the pivot to further improve camber stability.

The caster angle has been revised, as has the trail (wheel-axle offset), offering more linear handling and smoother steering.

New MR-04-specific front springs with different hardnesses are available as an option.

The front knuckles now feature a different king-pin mounting for greater freedom.

The car's 7 ball bearings have been replaced by 3 mm inner diameter ball bearings to reduce friction.

Pivot-wheel offset (scrub) is 1.5 mm shorter on the MR-04 than on the MR-03.

Steering responsiveness is improved, eliminating wheelbase variations in bends (and wheel arches in bodywork).

The new potentiometer offers precision and durability with a completely redesigned steering program for the best response and precision in MINI-Z history. The more precise steering control program allows for a variety of settings, thanks to the MR-04's exclusive I.C.S. software.

New motor mount design for sensored brushless motors.

Chassis height can be adjusted in three steps by changing the axle adjustment spacers to suit specific driving conditions. Cables can now be held on the motor mount for greater clarity.

The standard included ball differential optimizes rotation differences between the left and right rear wheels when cornering.

It also ensures moderate slippage to improve traction when excessive load is applied. The silver anodized finish of the aluminum parts creates a formidable style to match the performance.

Lower mounting of the batteries (or AAA-size rechargeable batteries) on the chassis means a lower center of gravity than on the MR-03. Combined with the shape of the chassis, this improves cornering stability, speed and control.
