The Brief
Built for Competition. Engineered for Confidence.
Brandon Watson, a BMWCCA Instructor and Street Survival Instructor, was preparing to take his experience behind the wheel into competitive racing with BMWCCA Club Racing and NASA GTS. To transform his BMW E36 M3 into a true wheel-to-wheel race car, the chassis needed a professionally engineered roll cage that met the requirements of his I Prepared class and NASA GTS competition rules.
Brandon came to HG Performance looking for more than a standard roll cage. He needed a custom solution that would meet competition specifications, integrate properly with the E36 chassis, and provide the protection, rigidity, and confidence required for serious track driving.
HG Performance designed and fabricated an 8.5-point full roll cage specifically for the BMW E36, using 1¾-inch × .095 DOM steel tubing and TIG welding throughout the fabrication process.
What We Did
Our team engineered and fabricated the complete roll cage in-house, tailoring the design to the BMW E36 chassis and its intended use in competitive motorsport.
The cage incorporates a main hoop with diagonal bracing and harness bar, rear vertical support bars, A-pillar bars with a knee bar, X-style door bars with clamshell gussets, A-frame rear auxiliary supports, and anti-foot-intrusion bars.
The fabrication process focused on both structural integrity and clean integration into the existing chassis. TIG welding was used throughout to achieve precise, strong, and consistent joints.
In addition to improving driver protection, the custom cage increased overall chassis rigidity. The result was a more responsive car with sharper reactions and more direct feedback through the chassis.

The Result
The completed roll cage transformed the BMW E36 M3 into a more competition-focused track car, providing the structural reinforcement and driver protection required for serious wheel-to-wheel racing.
The increased chassis rigidity also delivered sharper response and more direct driver feedback, helping Brandon better understand the car as he approached its limits on track.
Most importantly, the additional confidence provided by the properly engineered cage allowed Brandon to push the car harder. On his first drive after the cage was completed, he achieved a personal-best lap time at Chuckwalla Valley Raceway.
The result was a BMW E36 M3 that was better prepared for competition, more responsive on track, and engineered around the demands of its driver.
