We’re proud to offer the strongest, safest, best designed all 991.1 and 991.2 coupes, Carrera, Carrera S, Turbo and GT3 bolt in roll bar on the market. We design all of our bars with safety as the first concern. Don’t fall for the less expensive bars on the market. They don’t match our well thought out design and construction.

As with all Cantrell Motorsports half cages, our main goal is to provide safety and superior fit and finish. The rear mounts bolt to the upper rear shock tower factory roll bar provision providing the safest possible mounting point. The main hoop is mounted to the steel longitudinal frame structure which spans the width of the vehicle just like the factory bar. We designed this bracket to wrap around the steel frame using all oem attachment points providing the strongest design on the market without any drilling or modification other than very minor interior trimming to the side panel just like the factory does. The GT3 carpet already has a main hoop cutout for a roll bar and our bar fits that cutout perfectly.

We highly recommend CMS rollbars are only installed by shops that have experience installing roll bars. Cantrell Motorsports can most likely direct you to a installation shop in your area. Click on this link for complete Installation Instructions (991)
