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

Lightweight 7075-T6 Brake Post Arm Designed for MRX5

Made from 7075-T6 aluminium, this brake post arm fits the Mugen MRX5 chassis and is machined to increase rigidity without significant weight gain. It acts as an upgrade to the stock brake post arm, providing a firmer mounting surface for brake linkages and improved pedal consistency.

Fit and role: Arrowmax AM-MRX5-H2807-T is intended for MRX5 racers seeking tighter brake feel and a more dependable chassis response when changing brake settings. Treat it as an aftermarket component and verify fitment against your chassis before final installation.

Installation notes: the arm is precision machined; inspect mounting interfaces and use correct hardware from your kit or spares box. No chassis modification is assumed; check alignment and tighten fasteners following standard modelling practice.

Setup tips for better braking

• Introduce small brake bias adjustments after fitting to observe handling changes clearly rather than making multiple large alterations.
• Check linkage geometry and travel to avoid binding or accidental preload on the brake piston or shoes.
• Combine this upgrade with normal brake system tuning to assess how increased post stiffness influences lap consistency.
