Mugen MRX-5 One-piece Brass Engine Plate for Racing - Arrowmax AM-MRX5-H0772-V3  [AM-MRX5-H0772-V3]

Solid brass one-piece solution for MRX-5

The Arrowmax AM-MRX5-H0772-V3 is a V3 iteration of the one-piece engine mount built for the Mugen MRX-5 platform. Crafted from a single brass billet, the mount replaces multi-component mounts to cut down on movement at the engine mounting interface.

The V3 design introduces two additional engine attachment points versus the earlier release, boosting clamping points to assist in holding alignment during hard driving. The back plate end has been cosmetically updated to suit the new mounting layout while keeping MRX-5 fitment unchanged.

Installation tips: this part is intended as a direct replacement where the MRX-5 mounting footprint is present; reuse the original chassis mount hardware and engine bolts. During installation ensure alignment and fastener torque are checked for even clamping across the mount.

Tuning impact: because the part is a heavy brass one-piece, it increases mass around the engine mounting area which can change vibration patterns and power transfer into the chassis. Drivers often fit this mount to achieve a firmer engine seat and consistent positioning for track tuning.

For MRX-5 racers seeking a denser mounting option, the AM-MRX5-H0772-V3 supplies extra fixings and a revised rear plate profile to stabilise engine mounting during setup and track work.
