Mugen Seiki MTX-4 Rear Lower Mount Aluminium MTX4-45/TI by 3Racing  [MTX4-45/TI]

Rear lower aluminium replacement

This aluminium rear lower suspension mount serves as a scale replacement part for the Mugen Seiki MTX-4 chassis family. It is designed to be a direct swap that supports the rear suspension assembly and helps retain the chassis geometry during routine maintenance or setup changes.

Focus is on tuning and repeatability: the aluminium mount provides a rigid fixing point for the lower suspension arm at the back of the car, reducing play versus ageing plastics and aiding consistent alignment when you change settings. It is well suited to club racing and frequent track sessions.

Fitting guidance: remove the original rear lower mount from the MTX-4, check mounting faces and screw positions for compatibility, fit this aluminium component using the existing mounting points, and fasten hardware to a modest hand-tight setting before final inspection. Reassess wheel alignment and suspension movement after completing the install.
