GMG 991 LMS Harness/Roll Bar

GMG is proud to announce our latest addition to the GMG roll bar family for the 991 chassis. The GMG LMS roll bar features 4130 chromoly tubing to not only reduce weight, but to also increase chassis rigidity throughout the entire platform. While utilizing fully hand TIG and seam normalizing welds, this creates a perfectly clean welding environment for the strongest and lightest weight possible. The LMS roll bar is a 4 point fully closed front hoop section with an integrated cross brace and reinforced gusset plates. The design of this bar is an improvement over our RSR bar in terms of chassis stiffening and strength due to the main hoop mounting to the cross bulkhead of the chassis vs. the seat belt anchors on our RSR bar.

* Use of Chromoly tubing that has been carefully TIG welded and normalized at all joints.(meets requirements for POC/PCA)

* Designed to work with standard reclining seats or GT3 fixed back seats. (Not possible with the factory equipment /Motorsport Roll bar)

* Comes complete with all hardware to install. Mounts to the rear seat cross-bulkhead and rear strut towers with factory OEM provisions for mounting, (Factory bar requires drilling holes in floor and attaching plates)

* Available in standard durable satin black powder coated finish. Optional colors are available at an additional cost


* Although no cutting or drilling of the chassis is required, some interior trimming may be necessary. We recommend that you have the bar professionally installed at one of our authorized dealers or an experienced shop.
