MR-04 Front Bumper Replacement with IC Tag Support - Kyosho MZN-B03  [KY-MZN-B03]

Front Bumper for MR-04 Mini-Z

This RC-scale front bumper is made for Mini-Z MR-04 chassis applications and is supplied under the Kyosho MZN-B03 part number. It is a direct-fit replacement designed to retain the IC Tag mounting position and preserve body alignment for MAZDA 787B styled Mini-Z bodies.

Fitment leverages the MR-04 bumper mounting points so no chassis modification is required for standard MR-04 assemblies. Typical installation involves removing the body shell, aligning the bumper to the chassis mounts, and securing it with the existing fasteners using a small hex driver.

The bumper provides front-end protection against scale impacts and helps keep the body positioned correctly during tight pack racing or club track runs. For tuning, it assists in maintaining repeatable contact points between body and chassis so hobbyists can observe handling differences by watching body alignment and bumper clearance instead of changing suspension geometry.

Compatibility

Compatible with MR-04 Mini-Z chassis and intended for MAZDA 787B Mini-Z bodies that include the IC Tag feature referenced in the product name.
