Mugen MRX5 Aluminium Brake Post Arm 7075-T6 - AM-MRX5-H2807-T by Arrowmax  [AM-MRX5-H2807-T]

Machined 7075-T6 Brake Post Arm for MRX5

This machined 7075-T6 aluminium brake post arm is produced for the Mugen MRX5 chassis and balances added stiffness with low mass. It replaces the factory brake post arm to create a firmer connection for brake linkages and improve pedal feedback resolution.

Fit and role: the Arrowmax AM-MRX5-H2807-T is aimed at MRX5 users who want sharper brake response and more consistent chassis behaviour while adjusting brake settings. It is an aftermarket upgrade; verify compatibility with your chassis before fitting.

Installation notes: the arm is precision finished; inspect mounting areas and use the hardware from your kit or spares. No chassis cutting is assumed; confirm alignment and torque fasteners per usual hobby standards.

Practical tuning pointers

• Use the arm to make measured brake bias tweaks so you can attribute handling changes to single settings.
• Confirm linkage alignment and free movement after installation to prevent unwanted preload or binding.
• Test changes with your normal wheel and brake setup to determine how extra post stiffness affects lap-to-lap consistency.
