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

Aluminium rear lower mount upgrade

This aluminium rear lower suspension mount replaces the factory plastic component on Mugen Seiki MTX-4 chassis variants. It is a direct-fit replacement designed to support the rear suspension assembly and preserve chassis geometry during maintenance and setup work.

Best used for setup and servicing tasks, the aluminium mount provides a firmer pivot for the lower arm, reducing play seen in worn plastic parts and helping to keep alignment repeatable across runs. It suits club competition and regular track use where consistent geometry matters.

Fitment notes: remove the existing rear lower mount from your MTX-4, compare screw holes and mating surfaces, install this aluminium part using the same mounting points, and tighten fasteners by hand before performing final checks. After installation, verify suspension travel and wheel alignment during a short test session.
