CMS 981 Roll Bar Speed Yellow


FITS: 2013-17 Porsche Cayman (Base, S, GTS, GT4)


Hands down the best roll bar for your 981!

The CMS Performance 981 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 thicker 1.75" x .120" Docol R8 Advanced High-Strength Steel tubing, vs. the thinner-wall 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 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 981'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 can powder coat your roll bar in a color custom-matched to Porsche's 981 color palette, or you can choose from over 6,000 colors, candies, anodized-looks, or just black. Fully TIG welded by master welders, using superior materials, and custom powder coated in-house by Competition 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.

    Bolt-in Roll Bar 981

    I ordered the straight bar version (without the center hoop) since my car is gutted. Fitment is really good, and it looks great in Carmine Red against the silver (Rhodium silver) interior.
    Pete was a pleasure to work with. Always responded quickly to questions.

    Great product that fits nicely in our GT4. High quality construction. My mechanic said that some of the pre-cut trim parts needed a little jiggering to make fit, but in the end it looks and works great!
