StudioRSR E90 M3 Roll cage / Roll bar

StudioRSR has developed an outstanding rollcage / rollbar (half-cage) for the E90 M3 chassis to fulfill motorsport, HPDE, and track-day needs. Increased chassis rigidity and safety combined with a modern design befit of the newer models, makes the StudioRSR M3 roll cage the premium option available in the market. Designed and manufactured in-house, StudioRSR uses the latest manufacturing technologies to create this upgrade with **NASA Racing specifications** and wide-radius bends. There is zero metal crimping and zero tubing wall failure that is often seen from alternative roll cages. The Tesseract half-cage is 100% bolt-in featuring a 4-point optimum mounting design with form-fitted brackets specific to the E90 chassis. Professional installation is recommended, but installation is made easy with chromoly interlocking tubing clamps, zero welding, and all necessary hardware included. Additionally, street-spec classed vehicles can retain their rear seats if preferred. Available in-house at StudioRSR or shipped direct to you or your preferred Dealer/Installer internationally. The Tesseract half-cage consists of 2 main pieces making installation and shipping even easier. The development of the Tesseract roll cage / roll bar came about from customer demands from StudioRSR's track/enthusiast clientele from their previous generation E36 M3 or E46 M3. With several clients and some of our own staff now licensed and racing within several NASA & SCCA Racing, HPDE, and Time Trial classes, a professional motorsport solution was needed to maintain manufacturing quality in-house. As a specific benefit, the visual aesthetic matches the aggressive, modern design of the BMW E90 M3 perfectly. - 100% bolt-in- No Welding needed for installation- NASA Racing spec (as of 2016.5 rulebook **not sanctioned by NASA)- 4-point half-cage-  steel brackets form-fitted to the chassis- Made with latest manufacturing technologies- Wide-Radius bends = even stress distribution, no metal crimping, & no tubing wall failure- Designed with optimum bolt locations to factory mounting points- Signature designed Studio RSR - Proprietary CNC machined chromoly interlocking tubing clamps- Heavy-duty Chromoly steel .175" x .095 wall thickness all-around- All Grade-8 mounting hardware included- Installation instruction included- This product is intended for Off-Road use only- Product photos may vary from actual item- StudioRSR Terms & Conditions apply - 100% Made in USA- Powdercoated in Red, White, Yellow, or Black at no additional cost
