Front upper arm mount engineered for MRX5

This front upper arm mount and bush set is intended for the Mugen MRX5 front suspension to provide a simple route to refine chassis geometry. Machined from 7075-T6 aluminium, it includes adjustable POM inserts which let you move the roll centre without replacing major suspension components. The details that follow cover compatibility, materials, and tuning effects for circuit and club use.

Choose this mount when you want more controllable front-end behaviour; the POM inserts allow measured lateral shifts of the upper arm pivot that influence turn-in and dynamic weight transfer. Installation uses the MRX5's standard front arm mounting points and the original hardware where applicable.

Specifications

  • Item: Front upper arm mount with bush set
  • Material: 7075-T6 aluminium, POM inserts
  • Model Number: AM-MRX5-H2120
  • Compatibility: Mugen MRX5

A direct aluminium upgrade for Mugen MRX5 drivers who want to tweak front-end geometry and roll centre without extensive chassis modification.

Will this fit MRX5 kits from different years?

The mount follows MRX5 mounting dimensions used across common MRX5 releases. Confirm your car's front arm spacing against the part drawing, but it is intended to fit standard MRX5 variants.

How significant are handling changes after installation?

Handling changes are subtle and aimed at setup refinement. Adjusting insert position shifts roll centre and can improve turn-in or balance depending on other setup choices.

Does aluminium make the steering feel harsher?

Aluminium increases mounting rigidity which can sharpen steering feedback, but the POM inserts help retain some compliance and allow tuning to suit your preference.

Any tips for starting roll centre changes?

Begin with a single insert position change and test on familiar circuits. Record lap times and handling notes, then proceed in small steps until you find the desired balance between turn-in and mid-corner grip.
