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

7075-T6 Aluminium Brake Post Arm for MRX5

This 7075-T6 aluminium brake post arm is made for the Mugen MRX5 chassis and is CNC machined to increase stiffness while keeping weight low. It replaces the stock brake post arm to give a firmer mounting point for brake linkages and sharper pedal feedback.

Fit and role: the Arrowmax AM-MRX5-H2807-T is aimed at MRX5 builders who want crisper brake response and a more predictable chassis feel when fine-tuning braking. It is an aftermarket RC upgrade and should be checked against your chassis layout before installation.

Installation notes: the arm is precision machined so inspect the mounting faces and use the kit hardware or suitable spares. No chassis modification is assumed; confirm fitment before final assembly and tighten fasteners to standard hobby practice.

Practical setup pointers

• Make incremental brake bias changes with the new arm to isolate handling effects rather than altering multiple settings at once.
• Verify linkage geometry after fitting to avoid binding or added preload on the brake mechanism.
• Combine this arm with normal wheel and brake adjustments to evaluate how the added post stiffness affects pedal feel and lap consistency.
