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

Technical overview

Precision aluminium rear lower suspension mount engineered as a direct-replacement component for the Mugen Seiki MTX-4 chassis family. The part is intended to support the rear suspension assembly and maintain designed chassis geometry during setup and servicing operations.

Racing-focused use: the aluminium construction increases pivot stiffness at the rear lower arm mount, improving repeatability when adjusting toe and camber settings. This stability assists in achieving consistent lap-to-lap behaviour during competitive sessions and track testing.

Fitment procedure: remove the original lower mount, inspect the mounting faces and screw pattern for alignment, locate this aluminium unit in the same positions, and secure fasteners to a conservative hand-tight level before carrying out final checks with your preferred torque method. Validate suspension articulation and wheel alignment during initial track runs.
