The Kyosho MZW420C Front Upper Brace Set adds rigidity to the Mini-Z MR-03W front end, helping to control flex in the upper arm area. This makes steering inputs feel more direct and predictable on faster sections.
Reinforcing the upper arm keeps suspension alignment steadier during hard driving, which helps you maintain consistent lap times. The Kyosho MZW420C is a useful tweak for drivers chasing more repeatable handling.
Specifically produced for the MR-03W wide tread layout, this brace is easy to fit using common RC tools and does not demand major chassis alterations. It is a practical upgrade for improving front stability.
