The CMS Performance Roll Bar stands as the strongest, safest, and most beautifully constructed bolt-in roll bar available for the BMW G87 M2. Engineered to integrate seamlessly with any G87 variant, this premium safety solution delivers rollover protection while enhancing your car's motorsport-inspired aesthetic.
CMS Performance prioritizes safety and structural rigidity in every aspect of design. The entire roll bar is constructed from Docol R8 Advanced High-Strength Steel tubing, a material that outperforms competing options in nearly every measurable way. Docol R8 is 15% stronger than 4130 CrMo steel and 30% stronger than mild (DOM) steel used by other manufacturers. This superior material delivers exceptional tensile strength, energy dissipation, and occupant protection when you need it most.
The advantages extend beyond raw strength. Docol R8 excels in resistance to deformation, weld strength, and energy dissipation—qualities that directly translate to better crash performance and long-term durability.
The G87 roll bar features a one-piece main roll hoop with reinforced X-bracing and a horizontal harness bar. This design philosophy mirrors the engineering rigor found in the M3 itself, creating a bulletproof structure that protects occupants during rollover events and impacts.
The harness bar is specifically engineered to position racing harness shoulder straps at the optimal angle—between 0° and -20°—across most seating positions. This attention to detail ensures both safety and comfort during spirited driving.
Every CMS Performance G87 M2 roll bar bolts directly to the BMW's chassis, forming a rock-solid backbone for your protection system. The rearward kicker support angles are optimized for structural integrity and straightforward installation, while preserving your unobstructed rear view.
For those seeking additional strength and rigidity, optional X-brace gussets are available to further enhance the roll bar's performance. Whether you're tracking your M2 or simply want the peace of mind that comes with professional-grade safety equipment, the CMS Performance roll bar delivers on every front.
This G87 M2 also received the CMS Performance Rear Seat Delete. The seat installed with the roll bar is the Sparco QRT-R.
