Mini-Z MR-04 Rear Carbon Plate Upgrade MZW403B for Fine Tuning by Kyosho  [KY-MZW403B]

High-Stiffness Carbon Rear Plate Set

This Kyosho MZW403B carbon rear suspension plate set is an MR-04–compatible Mini‑Z upgrade created to let hobbyists control rear handling traits and chassis roll without changing the suspension geometry. Constructed from carbon fiber, the set includes three hardness options for stepwise rear tuning and balance adjustments.

The parts are tailored to the Mini-Z MR-04 platform and replace the stock rear plate to alter how forces are channelled through the chassis. Selected plate stiffness influences lateral roll and transient response, enabling adjustments from more stable understeer to increased rear rotation.

Fitting the plates requires basic rear pod disassembly and common Mini‑Z tools; no extra components come with the set. Use these plates in concert with spring, damper and weight tuning to reach the desired handling on indoor tracks and compact outdoor layouts.

Compatibility: Mini-Z MR-04 series.

Designed as a direct MR-04 rear tuning component, this carbon plate set adjusts rear handling via material stiffness and selectable hardness increments.
