CMS Performance Roll Bar for the Mustang Dark Horse 2024+ The Best Roll Bar On Earth for Ford's Track Day Monsters The CMS Performance Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market for the Dark Horse. In designing our roll bar, safety, strength, and structural integrity were our primary goals. That's why it is fully TIG welded from ultra-strong Docol R8 Advanced High-Strength Steel sized 1.75" diam x .095" wall, vs. the mild-steel tubing other companies use. Docol R8 is 30-35% stronger than DOM mild steel and even 10-15% stronger than 4130 CrMo steel. This allows CMS Performance to design a roll bar that is stronger and lighter weight. Precision CNC machined interlocking roll bar clamps, made to our specifications in the USA, make joining the main hoop and kickers easier during installation while giving the CMS Performance roll bar a premium, finished look. Adding an optional Shrader Rear Seat Delete Kit gives your roll bar installation a from-the-factory OEM look. American Made Safety for an American Icon Let's face it, safety is the primary reason to install a roll bar in your Dark Horse. So the CMS Performance Shelby Roll Bar is designed to place your harness shoulder straps at both the proper angle (0° to -20°) and distance to the driver.  The rear kickers bolt to a strong existing bulkhead, requiring no reinforcement plates beneath the floor pan. Our use of state-of-the-art Docol ultra-high-strength-steel tubing throughout allows us to keep the driver's rear view unobstructed by diagonal braces, which also keeps weight down. Every detail is engineered with safety and structural integrity as our primary goal. Precision Crafted and Custom Finished in OEM Colors The other reason to install a roll bar is because it really complements the aggressive, race-inspired styling of the S650 Dark Horse. We're gear heads, we get that. So each bar is crafted by hand by master fabricators, 360o TIG welded for the ultimate in strength and durability, and then custom powder coated in our facility (at no extra charge). We've color-matched powder to most of Ford's factory paint colors for a truly customized look, or you can choose from thousands of custom colors and finishes like the amazing Superchrome, giving your Shelby a personalized look that will last. Going from raw Docol tube stock to a gleaming finish, every roll bar is handcrafted by our most experienced cage- and race car builders. Nothing is left to chance. The CMS roll bar is designed to give you an unobstructed view through your rear window. None of your plastic interior trim needs to be removed or cut, just a little carpet that is hidden away. So if you ever need to put your car back to stock, it will look as though the roll bar was never there. Click Here for Installation Instructions Easier Installation and Lots of Options for Your Dark Horse Roll Bar Check out the GREAT installation video here! 1 Complete, detailed instructions make installation pretty simple (figure about two hours if you're reasonably handy; having a buddy helps!) All the supplied installation hardware is American made: Grade 8 mounting hardware and an industrial carbide drill bit. So you don't have worry that you don't have what you need for a flawless installation. You can add six-point or four-point harnesses to your order to take full advantage of the safety upgrade your roll bar represents. The CMS Performance Sub Strap + Lap Belt Mount makes securely installing your racing harnesses easy. Check out the drop-downs above. Many customers also add CMS Locking Harness Collars to keep harness shoulder straps right where you want them (they're not required for safety, but a lot of people like the look.) 1 Note: Thank you to our customer "@1_trickpony_" for putting in the time and effort to shoot and edit a fantastic installation video!
