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

Precision 7075-T6 Brake Post Arm for MRX5

This machined 7075-T6 aluminium brake post arm fits the Mugen MRX5 chassis and is finished to raise rigidity without adding unnecessary mass. It serves as an upgrade to the original brake post arm, providing a firmer anchor for brake linkages and improved pedal clarity.

Fit and role: Arrowmax AM-MRX5-H2807-T targets MRX5 drivers chasing more immediate brake response and a steadier chassis feeling during braking adjustments. Treat it as an aftermarket component and confirm fit on your specific chassis layout before installation.

Installation notes: the component is precision machined; check mating surfaces and use appropriate kit hardware or spares. No chassis machining is implied; trial-fit parts and tighten fasteners following normal hobby practice.

Tuning recommendations

• Introduce small changes to brake bias with this arm to understand its effect on corner entry and traction.
• After fitting, check linkages for smooth travel and correct lever geometry to prevent binding.
• Use standard wheel and brake setup trials alongside the arm to see how increased post stiffness alters pedal feel across laps.
