Mugen MRX-5 Rear Upper Arm Holder A Upgrade - Arrowmax AM-MRX5-H2113  [AM-MRX5-H2113]

Upper arm holder for MRX-5 rear end tuning

This Arrowmax AM-MRX5-H2113 unit is a rear upper arm holder produced for the Mugen MRX-5 chassis. It provides the fixed point for the rear upper suspension arm and has direct influence on the rear linkage geometry and wheel camber behaviour.

Fitting is generally simple for those familiar with MRX-5 maintenance: remove the original holder, check the mating surfaces and screw types on your MRX-5, and normally retain the factory fasteners unless otherwise specified. After installing, check for equal alignment on both sides and ensure full suspension travel without interference.

In setup terms this component sets the upper pivot and so affects roll centre and camber progression. Replacing the holder or altering its position should be done incrementally with test laps to evaluate changes to traction and corner entry.
