StudioRSR has developed an outstanding rollcage / rollbar (half-cage) for the M4 (F82 chassis) to fulfill motorsport, HPDE, and track-day needs. Increased chassis rigidity and safety combined with a modern design befit of the BMW M4, makes the StudioRSR Tesseract roll cage the premium option available in the market.

Update 1 Nov. '16: Chromoly 4130 lightweight version now available.
Update 2 Nov. '16: Choose your desired Rear-Leg design (Tesseract bent or Straight leg)
Update for F80 M3 owners: The Cartesian F80 M3 Roll Cage is now available

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 F82 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 now moving into the BMW M4 from their previous generation E36 M3, E46 M3, E90 M3, or E92 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 Tesseract's visual aesthetic matches the aggressive, modern design of the BMW F82 M4 perfectly.
