The CMS Performance Roll Bar is the strongest and safest bolt-in roll bar on the market for your Porsche 981 Cayman (base, S, GTS, and GT4). In designing our roll bar, safety and structural rigidity were our primary goals. That's why we use thicker 1.75" x .120" wall 4130 CrMo tubing, which meets or exceeds PCA, SCCA, and NASA tube-size requirements (to meet Time Trial rule requirements, you may need to select the diagonal cross bar configuration).

Our harness bars are designed to place harness shoulder straps at the proper angle (0° to -20°) to the driver, regardless of seat position, withoutcutting the center carpeted "hump". This design also provides an ideal mount for a Smarty Cam. Our use of thicker CrMo tubing throughout allowed us to keep the driver's rear view unobstructed by rear diagonal braces. This also allows unfettered access to the engine cover with the roll bar in place.

The rear kickers bolt to the rear shock towers, providing the safest possible mounting point. This adds tremendous rigidity to the rear chassis and suspension. The main roll hoop is mounted to the frame structure across the rear bulkhead.

Fully TIG welded by a master welder, the integrity, fit, and finish of the Competition Motorsport roll bar is unsurpassed. We offer a full range of powder-coat colors to match your Porsche, or satin black for a more stealthy appearance -- all included in the price.

FITS: 2012-2016 Porsche Cayman base, S, GTS, and GT4

    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!
