The CMS Performance Roll Bar for the BMW G82 M4 represents the pinnacle of safety engineering and craftsmanship. Designed specifically for the newest generation M4, this bolt-in roll bar combines structural integrity with aesthetic excellence, seamlessly integrating into the car's luxury sport interior.
CMS Performance engineers prioritize occupant safety above all else, which is why they selected Docol R8 Advanced High-Strength Steel tubing for every component of this roll bar. This premium material delivers unmatched performance compared to alternatives found in other bolt-in systems. Docol R8 is 15% stronger than 4130 CrMo steel and 30% stronger than mild DOM steel, offering superior resistance to deformation, exceptional weld strength, and enhanced energy dissipation in impact scenarios.
The one-piece main hoop features fully-integrated X-bracing and bolts directly to the chassis, creating a rigid backbone that distributes forces efficiently throughout the vehicle structure. Rearward "kicker" supports are strategically optimized to provide critical support during roll-over events while maintaining an unobstructed rear view—a crucial balance between protection and practicality.
The integrated harness bar is meticulously designed to position racing harness shoulder straps at the proper angle (0° to -20°) relative to the driver's shoulders, regardless of seat position. This attention to detail ensures that occupants remain properly secured and protected in high-performance driving situations.
For M4 owners who demand the strongest, safest, and most beautifully constructed roll bar available, CMS Performance delivers an exceptional solution that honors both the car's engineering excellence and the driver's safety.
