The Kyosho MZW420C Front Upper Brace Set is made to reduce front-end flex on Mini-Z MR-03W models, locking the upper arm area for steadier handling. That extra stiffness gives more consistent feedback through quick direction changes.
By reinforcing the upper arm zone, the Kyosho MZW420C helps keep suspension geometry stable during hard cornering. That reduces unpredictable toe change and makes it easier to hit the same line lap after lap.
This brace is specifically for the MR-03W wide tread configuration and fits without major chopping or fabricating. Installation is straightforward for most hobbyists using standard RC tools and basic mechanical skills.
