A Superior Roll Bar For Porsche's Track-Day Animal
The CMS Performance 991 Roll Bar is the strongest, safest, and highest quality bolt-in roll bar on the market for your GT3 or GT3RS, period. In designing and building the CMS roll bar, safety and structural rigidity are our primary goals. That's why we fully TIG welded 1.75" x .120" wall Docol R8 Advanced High-Strength Steel tubing instead of the less-expensive, but inferior, 4130 CrMo others use. It's why we use the strongest chassis mounting points and cross-brace the main hoop. Even if you're running track days, you want the only roll bar that meets (or exceeds) PCA, SCCA, and NASA requirements for Time Trial racing!
The CMS roll bar places your safety harness shoulder straps at the proper angle (0° to -20°) and distance (as close as possible) to the driver, regardless of seat position. Our use of thicker Docol tubing and main-hoop cross bracing gives you an unobstructed rear view and safety superior to that of other products we've seen for sale.
CMS rear kickers bolt to the 991's rear shock tower (where the factory racing roll cage mounts), the safest, strongest mounting points. This adds rigidity to the chassis and suspension. The main roll hoop is mounted to the steel frame structure beneath the vehicle just like the factory cage, using the factory carpet cut-outs.
Fully TIG welded by master welders and powder-coated on-site by CMS Coatings, the structural integrity, fit, and finish of the CMS Performance roll bar is unsurpassed. We offer a full range of powder-coat colors to match your Porsche (including, of course, matte black if stealth is more your thing) all included in the price of the CMS roll bar.
Superior engineering, design, quality, safety, and appearance at an affordable price, backed by our legendary customer service all add up to this: you can pay a lot more for a roll bar, but you'll only get the best from CMS.
