The Kyosho MZW419C Front Upper Brace Set II reinforces the upper arm area of the MR-03 Narrow chassis to reduce flex. This upgrade supports a firmer chassis feel that helps with accurate steering and repeatable lap times.
Drivers who compete on tight indoor circuits will notice improved control when entering corners and under acceleration. The brace helps stabilise the front end so you can place the Mini-Z with more confidence on low-grip or technical layouts.
Designed specifically for MR-03 Narrow models, the Kyosho MZW419C fits without altering the basic layout. Fit it as a first mechanical tweak, then make small setup changes to shocks or toe to match your driving style.
