GMG Racing 991 and 991.2 LMS Rollbar


The GMG LMS roll bar is made from 4130 Chromoly tubing to not only minimize added weight, but to also increase the chassis’ rigidity.  Each bar is precisely TIG-welded and normalized right here in Southern California.  The 4-point LMS design features an X-braced main hoop with rearward extending arms and diagonal bar.  The front legs are bolted down directly to a structural cross-member, while the rear arms are attached (via reinforcement plates) to the rear shock towers.  Through track testing we found this design to provide the best trade-off between increased structural support and additional weight.

Please note that rollbars do not include final shipping charges. Because of the size and complexity of freight, shipping is done on a individual basis. A separate invoice will be sent post–purchase for products bought online, or to get a shipping quote beforehand, please email orders@autocouturemotoring.com.


  • The system is TIG-welded using Chromoly tubing and increases the structural rigidity of the chassis by bracing 4 structural points together. (Meets requirements for POC/PCA for HPDE)
  • Designed to work with standard reclining seats, light-weight bucket seats and aftermarket bucket seats with no interference in seat travel
  • Installation is 100% "bolt-in". No fabrication required. Minor trimming to the carpet is necessary. (Factory bar requires drilling holes in floor and attaching plates)
  • Comes complete with all hardware needed to install.
  • **Installation is available at our Southern California location, or at any of our world-wide network of authorized dealers.

Vehicle Fitment includes all 2012-2018 Porsche 911 Models (991 Chassis)
