Kyosho MZW706N Narrow MR-04 Aluminum Upper Brace Performance Part  [KY-MZW706N]

Refine MR-04 Chassis Feel with the Kyosho MZW706N Upgrade

The Mini-Z MR-04 responds dramatically to small setup changes. The Kyosho MZW706N Aluminum Upper Brace stiffens the chassis to cut flex and sharpen turn-in, helping drivers get repeatable lines on both tight indoor circuits and smoother surfaces.

What an Aluminum Brace Adds to Your Setup

At club pace, reduced chassis flex equals more predictable handling. Swapping the stock MR-04 brace for the MZW706N reduces deformation under load, which improves mid-corner stability and makes suspension tuning more effective.

Installation Tips from Experienced Builders

When fitting the MZW706N, use a torque-consistent approach to the mounting screws and recheck after a few runs. This brace is especially useful for crews running higher corner speeds or firmer spring rates where chassis torsion can upset balance.

Keen Fitment and Quality from Kyosho

Kyosho's manufacturing tolerances mean the MZW706N integrates neatly with the MR-04 platform, offering a snug fit without interfering with other components. The result is increased stiffness without compromising the Mini-Z's lightweight character.

For MR-04 pilots aiming for tighter handling and more confidence through corners, the Kyosho MZW706N is a sensible, well-made upgrade that improves chassis response.
