The Kyosho MZW419C Front Upper Brace Set II adds targeted support to the MR-03 Narrow chassis, cutting flex at the front upper arm. The result is a firmer front end that responds more directly to steering inputs.
RC drivers looking for more consistent cornering and better turn-in often use this brace as a straightforward mechanical upgrade. It helps reduce unpredictable movement so you can focus on line and throttle control on fast layouts.
Built for MR-03 Narrow variants, the Kyosho MZW419C installs easily and works with common Mini-Z setups. It is a useful first upgrade before moving on to more detailed tuning adjustments.
