Cartesian BMW F80 m3 rollcage / harness bar
StudioRSR has developed an outstanding 100% Bolt-In rollcage / rollbar (half-cage) for the BMW F80 chassis. A functional aesthetic use with rear-seat compatibility and increased chassis rigidity match the upgraded characteristics of the F80 BMW. The StudioRSR Cartesian roll cage is the premium option available in the market. Designed and manufactured in-house, StudioRSR uses the latest manufacturing technologies to create this upgrade with *Optional 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 Cartesian half-cage is 100% bolt-in featuring a 4-point optimum mounting design with 6 form-fitted brackets specific to the F80 chassis. Professional installation is recommended, but installation is made easy with Propriety CNC machined tube-integrated chromoly 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 Cartesian half-cage consists of 2 main pieces making installation and shipping even easier.
The development of the Cartesian roll cage / roll bar came about by popular demand from StudioRSR’s Tesseract BMW M4 roll cage. 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 Tesseract’s visual aesthetic matches the aggressive, modern design of the BMW F80 M3 perfectly.
