The Kyosho MZW420C Front Upper Brace Set is crafted to stiffen the upper arm area on Mini-Z MR-03W cars, cutting down on unwanted movement that affects steering precision. That increased stiffness helps the car hold its line under load.
With the Kyosho MZW420C fitted, the front suspension geometry stays more stable during aggressive cornering, which supports repeatable lap times and crisper turn-in. It suits drivers who value predictable handling in technical sections.
Intended for the MR-03W wide tread setup, this brace is designed for a straightforward retrofit with common RC tools. Check fitment against your current components before assembly to ensure a clean installation.
