CMS Performance Roll Bar BMW G82 M4

The CMS Performance Roll Bar is the strongest, safest, most beautifully constructed bolt-in roll bar on the market for the newest BMW M4 (the G82). CMS Performance engineers put a premium on safety and structural integrity, creating an exceptional design that integrates perfectly with the M4's luxury/sport interior. CMS Performance uses advanced Docol R8 Advanced High-Strength Steel tubing throughout every roll bar, giving them unequalled tensile strength and occupant protection. Docol R8 is 15% stronger than 4130 CrMo steel and 30% stronger than mild (DOM) steel used in other bolt-in roll bars. It is superior in every way: resistance to deformation, weld strength, and energy dissipation. The one-piece main hoop with fully-integrated X-bracing and harness bar bolts directly to the chassis, forming the backbone of the CMS Performance Roll Bar. Rearward "kicker" supports are optimized for support in a roll-over event while maintaining an unobstructed rear view. The harness bar is specifically designed to locate racing harness shoulder straps at the proper angle (0° to -20°) to the driver's shoulders regardless of seat position. FEATURES: Optional premium custom-designed rear seat delete for a factory-finished appearance Precision-cut mounting plates Designed, manufactured, and finished in the USA American-made CNC machined solid steel interlocking joints Allows full seat travel with virtually any seat   Installation requires removal of the factory rear seats. A rear seat delete kit is recommended but not required for roll bar installation.
