We are proud to have continued our tradition of offering high-quality harness bars for late model Porsche’s.  The GMG LMS harness bar is made from Docol R8 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.

Shipping:

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

Powder Coating:

• Standard colors include : Satin Black
• Specialty colors include Red, yellow, silver, and white but are not limited to: Lava Orange, Lizard Green, Chalk, Miami Blue Etc. *Please call to inquire on these*

• The system is TIG-welded using Docol R8 tubing and increases the structural rigidity of the chassis by bracing 4 structural points together. (Meets requirements for POC/PCA for HPDE)
• Much lighter, and stronger than other roll bars (4130 Chromoly, DOM tubing)
• 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.
