BMW F97 X3M / F98 X4M Carbon Strut Brace Retrofit

Upgrade your BMW F97 X3M or F98 X4M with the genuine OEM carbon fiber strut brace originally introduced on 11/2019 and later production models. Early X3M and X4M vehicles were equipped with an aluminum strut brace from the factory; this retrofit allows owners of pre-production-update cars to install the same carbon unit BMW uses on current-production vehicles. As a direct OEM component, fitment is exact and quality is uncompromised.

Constructed from high-grade carbon fiber, this strut brace is significantly lighter than the aluminum unit it replaces while offering equivalent structural integrity. The carbon construction delivers a premium underhood appearance consistent with the performance character of the X3M and X4M platforms. Installation is a direct swap with no modification required.
