4-Point Bolt-In Half Roll Cage

The StudioRSR roll cage is a premium, 4-point bolt-in half-cage engineered to meet the demands of track-day enthusiasts, HPDE participants, and competitive motorsport drivers. Designed specifically for the BMW G80 M3 chassis, this roll cage significantly increases structural rigidity and cabin safety without the need for chassis welding. It is constructed using heavy-duty 1.75" x .120" wall DOM steel, with optional 4130 Chromoly available, ensuring both strength and integrity. Manufacturing relies on wide-radius bends that eliminate common issues like metal crimping and tubing wall failure found in alternative products. The system includes six form-fitted steel brackets that align with factory mounting points, and it is supplied as a 2-piece assembly for easier shipping and installation. Proprietary 2-piece chromoly interlocking tubing clamps facilitate a precise fit, and all necessary Grade-8 mounting hardware is included. Professional installation is highly recommended for proper securement and safety compliance. This product is strictly intended for off-road use only. Please note that while the Tesseract bent leg version is optimized for Street/HPDE specifications, the straight leg version adheres to the 2019 NASA Racing rulebook, though it is not inherently sanctioned. Installation may require the removal of interior panels and seats due to the tight clearances of the G80 interior.
