The CMS Performance Roll Bar is the strongest, safest, most beautifully constructed bolt-in roll bar on the market for the BMW M4 and M4 Competition. Engineered with a premium on safety and structural rigidity, the exceptional design integrates perfectly with the M4's luxury/sport interior. CMS uses only advanced Docol R8 Advanced High-Strength Steel tubing throughout each roll bar, giving you 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.
Our 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.
Cutting Edge Materials and American-Made Craftsmanship
The CMS Performance BMW M4 Roll Bar is designed to bolt directly to the M4 chassis strong points without the need for any modification of existing interior trim or use of backing plates. Adding a CMS custom designed rear seat delete gives the whole installation a clean, factory appearance.
Full 360-degree TIG welding throughout gives the CMS Performance Roll Bar unsurpassed strength and durability. Each roll bar includes custom powder coating in your choice of matched M4 factory colors. You can choose an amazing technical color like Superchrome! Or satin black for a more stealthy appearance. We have over 5,000 custom powder coat colors for a truly customized look.
Our unwavering focus on using cutting-edge materials, unsurpassed design & construction, and premium fit & finish has taken CMS Performance Roll Bars to the top of the industry. The BMW M2 roll bar is the latest addition to our growing catalog, bringing safety, integrity, and beauty to customers taking their M2 to the track!
