CMS 718 Roll Bar Sapphire Blue


FITS: 2018 Porsche Cayman (Base, S, GTS)

Hands down the best roll bar for your new 718!

The CMS Performance 718 Roll Bar is the strongest, safest, and most beautifully constructed roll bar on the market for your Cayman. In designing our roll bar, safety and structural rigidity were our primary goals. That's why we use premium Docol R8 Advanced High-Strength Steel sized 1.75" x .120", vs. the thinner-walled 4130 tubing others use. So our materials meet/exceed PCA, SCCA, and NASA requirements (to meet Time Trial rule requirements, you must select the diagonal cross bar configuration).

Our harness bars are designed to place harness shoulder straps at the proper angle (0° to -20°) and distance to the driver, regardless of seat position. Yet our bar also requires no cutting of the carpet in your car -- replacing your carpet is incredibly expensive should you want to return the car to stock in the future. Our design provides an ideal mount for a Smarty Cam video camera. Our use of thicker state-of-the-art Docol tubing throughout allows us to keep the driver's rear view unobstructed by rear diagonal braces, giving you unfettered access to the engine cover with the roll bar in place. Our competitors make you remove part of your roll bar to get at your engine.

The CMS roll bar's rear kickers bolt to the 718's rear shock towers, the safest, strongest possible mounting point. This adds tremendous rigidity to the chassis and suspension. The main roll hoop is mounted to the frame structure across the rear bulkhead for lighter weight and superior strength.

We offer over 6,000 powder-coat colors and finishes, including those custom-matched to Porsche's 718 Cayman color palette. Fully TIG welded by a master welder, using superior materials, and custom powder coated in-house by CMS Coatings. The design, strength, fit, and finish of the CMS roll bar all add up to this: you can spend more on a roll bar, but you only get the best from CMS.
