VTT F9X X3/4M Carbon Fiber Strut Braces

Description

VTT Carbon Fiber Strut Bars – BMW F97/F98 X3M & X4M

While BMW did an outstanding job engineering the F9X X3M and X4M platforms, the factory strut bars leave much to be desired. The OEM stamped steel pieces lack visual appeal and feel like an afterthought on an otherwise well-designed performance machine.

At VTT, we set out to change that. We removed the stock bars, put our engineers to work, and developed a replacement that is both beautiful and functional. The result is a 100% pre-preg carbon fiber strut bar system bonded to CNC-machined billet 6061-T6 aluminum ends, anodized in a range of premium finishes.

The transformation is immediate — a sleek, motorsport-inspired look that’s half the weight of the factory setup while maintaining full structural integrity.

Key Features

• True Pre-Preg Carbon Fiber Construction – Not a carbon wrap or overlay; genuine structural carbon fiber for maximum strength and weight savings.

• CNC-Machined Billet Ends – Precision machined from 6061-T6 aluminum and anodized in your choice of color.

• Lightweight Design – Each carbon bar weighs roughly half of its factory counterpart.

• Direct Bolt-On Fitment – Installs using factory mounting points with no modification required.

• Perfect Complement – Designed to pair seamlessly with the VTT Carbon Fiber Center Strut Bar for a complete underhood package.
