The Eventuri BMW G8X M2 / M3 / M4 CSL Carbon Strut Brace is engineered to increase chassis rigidity while adding a highly distinctive carbon fiber structural element to the S58 engine bay. Designed for the BMW G87 M2, G80 M3, and G82 / G83 M4, the brace combines pre-preg carbon fiber construction with precision-machined metal hardware for a lightweight, rigid, and highly integrated upgrade.

Rather than serving as a purely visual engine-bay component, the Eventuri CSL Carbon Strut Brace is designed to contribute to structural stability under load. Its carbon construction provides a high strength-to-weight ratio, helping reduce chassis movement during aggressive cornering and transient load changes while maintaining minimal added mass.

The brace features a complex surface geometry with raised sections, deep fillets, and sculpted transitions engineered to help distribute loads across the structure. This geometry also creates a strong visual connection across the engine bay, framing the S58 engine and surrounding intake components with a motorsport-inspired design.

Integrated CNC-machined stainless steel inserts provide precise mounting points within the carbon structure, while custom 316 stainless steel hardware offers long-term corrosion resistance and durability. Satin anodized inserts within the mounting pockets add contrast against the carbon weave and complete the hardware integration.

The Eventuri CSL Carbon Strut Brace is available in Gloss or Matte carbon fiber finishes, allowing the brace to be matched with factory or aftermarket engine-bay carbon components. For vehicles equipped with the V1 Eventuri G8X Intake System, an additional intake retrofit kit is required to provide the necessary clearance and compatibility.

For additional information on the engineering, structural design, and validation behind the brace, read our Eventuri CSL Carbon Strut Brace Engineering Deep Dive.
