Mugen Seiki MTX-4 Aluminium Barke Bar by 3Racing MTX4-43/TI  [MTX4-43/TI]

MTX-4 aluminium brake bar overview

This aluminium Barke Bar is a scale RC chassis component intended for the Mugen Seiki MTX-4 platform and supplied by 3Racing as part number MTX4-43/TI. It serves as a direct-fit upgrade that focuses on reducing part flex and refining front-end feedback during dynamic cornering on carpet or dirt tracks.

Functionally this part is positioned as a tuning item: replacing a softer OEM plastic bar with an aluminium unit changes how the front suspension and steering respond under load, offering a firmer connection between the chassis and the front suspension pickup points. That effect assists drivers who want crisper initial turn-in and more consistent steering across repeated laps.

Installation is straightforward for technicians familiar with MTX-4 maintenance: remove the original bar using the stock mounting screws and transfer any existing spacers or bushings to the aluminium unit, then fit to the same mounting points. Take care not to overtighten fasteners to avoid thread damage and verify alignment before running. Small adjustments to toe, camber, or shock settings are often used in conjunction with a stiffer bar to tune overall handling balance.
