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.
