• Porsche Cayman GT4RS, 718 (2023+)

The First and Best Roll Bar Designed for the GT4RS

CMS Performance has done it again! We've designed the new CMS Performance Roll Bar for the Porsche 718 Cayman GT4 RS to be the strongest, safest, and most beautifully constructed roll bar on the market. In designing the CMS Performance Roll Bar for your Porsche GT4 RS, safety and structural rigidity are, as always, our primary concerns. That's why we use 1.75 x .095" Docol R8 Advanced High-Strength Steel tubing for the main hoop and kickers and a 1.5" harness cross bar minimize weight. Docol R8 is stronger and more ductile than the Chromoly tubing other manufacturers use.

The CMS Performance Porsche GT4 RS Roll Bar features a 1.5" diameter cross-bar designed to put your racing harness shoulder straps at the correct angle (0° to -20° front-to-back) and distance (about 8 inches) relative to the driver. Yet the CMS roll bar requires no cutting through the carpeting in the middle of your interior (replacing this carpet is expensive if you ever want to return your car to stock). This also provides an ideal mount for a HD Racing Video camera.

Attention To Detail Is The Hallmark Of CMS Performance

Our use of Docol R8 tubing throughout also lets us to keep the driver's rear view unobstructed by the rear diagonal bracing typically used to support weaker roll bars. This also gives you unfettered access to the engine cover without removing any part of your roll bar. Other roll bars require partial removal to get at your engine -- not ideal in a car that sees track time.

The CMS Performance Roll Bar for the Porsche GT4RS is designed with rear kickers that route over the incredible carbon fiber intakes and engine cover and bolt to the GT4 RS rear shock towers. These are the safest, strongest possible mounting points, adding rigidity to the chassis and suspension. The main roll hoop is mounted to the frame structure across the rear bulkhead for light weight and superior safety.

Exceptional Color Options Only From CMS Performance

CMS Performance will powder coat your roll bar in a brilliant color that's been custom-matched to Porsche's GT4RS OEM color palette¹. We also offer powder coating in technical colors such as the amazing Superchrome! Or you can go with our rich satin black for a more stealthy look.

The Best Porsche GT4RS Roll Bar At The Best Price

Fully TIG welded by master welders using superior materials, the design, strength, fit, and finish of the CMS Performance GT4RS Roll Bar is second to none. You can certainly spend more on a roll bar, but can you only get the best from CMS Performance.

Add Premium Racing Harnesses to Your Porsche GT4RS

Add six-point Schroth Enduro 2x2 GT4, Schroth Flexi 2x2 GT4, or Sabelt Silver Series GT4 harnesses to your order and save!

Or you can add either the Schroth Profi II ASM GT4 or Sabelt Porsche GT4 four-point harnesses for one or both seats. Both the six-point and four-point harnesses are specially designed to bolt directly to your Porsche GT4RS lightweight carbon bucket seats.

If you're installing six-point harnesses in your Porsche, we strongly recommend adding the CMS Performance Sub Strap Mount to your seats. This custom-made steel sub strap mount provides a solid, properly located anchor for your anti-submarine strap, and it's easy to install at the same time as your roll bar.
