CMS Performance Clubsport Roll Bar For Porsche 991 GT3 & GT3RS

New Ultimate Roll Bar for the Porsche 991 GT3 and GT3RS

The CMS Performance Clubsport Roll Bar is a new variant of our incredibly popular GT3/GT3RS roll bar. Re-designed with steel gusseting and high-strength support tubing is added to the top and bottom of the X-brace and to all four corners, the CMS Performance Clubsport Roll Bar takes rigidity and strength to another level.

This is the strongest, highest quality bolt-in roll bar on the market for the Porsche 991 GT3 and GT3RS, period. In designing and building the CMS Performance Clubsport roll bar, structural rigidity and impact protection were our primary goals. This roll bar is fully 360o TIG welded, the main tubing is 1.75" Docol R8 Advanced High-Strength Steel. CMS is the only roll bar manufacturer to employ this modern material. The support tubing is Docol R8 as well, and the gussets are machined from steel plate.

CMS Performance tailors the GT3/GT3RS Clubsport roll bar to take full advantage of the strongest chassis mounting points in the Porsche 991 GT3/GT3RS . The main roll hoop is X-braced and gusseted, with a single tube cross-bar providing lateral strength that's also used for mounting racing harness shoulder straps.

Attention To Detail Is The Hallmark Of CMS Performance

Proper angle for racing harness shoulder straps how to install your harnessThe cross-bar on the CMS Performance Clubsport Roll Bar for the Porsche 991 GT3 and GT3RS lets you attach your racing harness shoulder straps at the proper angle (0° to -20° front-to-back) and distance relative to the driver and passenger, regardless of seat position.

The CMS Performance Clubsport Roll Bar was designed to leave your rear view unobstructed by additional bracing that other roll bars require due to the use of inferior materials.

CMS Performance also features a unique three-piece rear kicker that bolts to the Porsche 991 GT3/GT3RS rear shock towers (where the factory GT3 Cup Car roll cage mounts). These are the strongest rear mounting points, and also add rigidity to the chassis for more precise handling. This kicker design is incredibly strong while also being a breeze to install (typical one-piece designs can be a nightmare to install). The main roll hoop is mounted to your Porsche's steel frame structure beneath the vehicle just like the factory Cup Car cage.

Built Like a Tank, Finished Like a Porsche

Designed using the same guidelines as a full racing roll cage and fully 360TIG welded by our chassis fabricators and master welders, the CMS Performance Clubsport Roll Bar for the Porsche 991 GT3 and GT3RS is unsurpassed in quality, durability, and structural integrity. Each roll bar is professionally powder-coated in-house to guarantee fit and finish no other manufacturer can match. This also lets us use powder coat colors we've matched to Porsche GT3 and GT3RS OEM paint colors for a truly customized aesthetic. We also offer custom technical powder coat finishes like the amazing Superchrome! Or you can choose our rich satin black powder coat for a more low-key installation. Powder coating any color you choose is included in the price of your CMS Performance roll bar.

Don't Settle For Anything Less Than The Best

Thoughtful engineering and design, superior materials, masterful fabrication, and beautifully customized finishing. That's the CMS Performance way of doing things. Backed by our legendary customer service, it all adds up to this: you can pay more for a roll bar, but you can only get the best from CMS.

Add Premium Racing Harnesses To Your Porsche

Add six-point Schroth Enduro 2x2 GT3, Schroth Flexi 2x2 GT3, or Sabelt Silver Series GT3 racing harness to your order and save! These harnesses are specifically designed for the Porsche 992 GT3 and GT3RS and will bolt to your factory lightweight carbon bucket seats.

Or you can add four-point Schroth Profi II ASM GT3 or Sabelt Porsche GT3 4 Point harnesses, ideal for the Porsche 992 GT3 and GT3RS passenger seat that doesn't have a factory sub-strap pass through.

With six-point harnesses, we strongly recommend using the CMS Performance Sub Strap Mount to provide a solid, properly located anchor for your anti-submarine straps. The CMS Performance Sub Strap Mount is simple to install at the same time you're installing your roll bar!

Straightforward Installation Takes The Headache Out Of Roll Bars

We've been through more than a few wrestling matches installing bolt-in roll bars in street cars. Fortunately, we used that experience to design the CMS Performance Roll Bar for the Porsche 992 GT3 and GT3RS to be a lot less frustrating to install. Check out the installation instructions here. We hesitate to go so far as to say it's easy, but we'll say it isn't hard if you have a friend and some basic tools.
