BMW F30 Rear Subframe Reinforcement Bracket Kit with 034Motorsport Billet Inserts

Overview

Complete retrofit kit that installs the F32 coupe rear subframe V-brace on F30 sedans using factory BMW parts. Includes F32 rear subframe V-brace assembly, 034Motorsport billet aluminum subframe mount inserts to eliminate void space, and all necessary hardware (torx screws, bolts, fasteners). Significantly improves rear-end responsiveness and chassis rigidity by reducing unwanted subframe movement. Ideal for vehicles with upgraded suspension components like larger sway bars and upgraded shocks/springs. Direct bolt-on installation using factory mounting points.

Installation summary

This installation requires intermediate mechanical skill and is best suited for DIY enthusiasts comfortable with suspension work who have access to a lift and proper jack stands. The direct bolt-on process utilizes factory mounting points to install the F32 V-brace and 034Motorsport billet subframe inserts, and you will need standard metric hand tools along with spring perch tools and a torque wrench to properly tighten all new hardware. The most important thing to watch out for during installation is ensuring the billet inserts seat completely flush within the subframe bushings before final torquing. Please note that a professional chassis alignment is strictly required immediately following the installation to correct suspension geometry, and any associated ride height adjustments should be made if your vehicle is equipped with coilovers.
