Mini-Z Racer MR-04EVO2 Chassis Set (W-MM/5600KV)

While retaining elements of the excellent MR-03 layout, the 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. 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.
