Tesseract BMW 4 series roll cage / roll bar for BMW 428i | 435i

Product Description

BMW roll cage / roll bar by StudioRSR

StudioRSR has developed an outstanding rollcage / rollbar (half-cage) for the BMW 4 series (428i and 435i models) to fulfill motorsport, HPDE, and track-day needs. Increased chassis rigidity and safety combined with a modern design befit of the BMW 4 series, makes the StudioRSR Tesseract 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 4 series 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 4 series from their previous generation BMW track cars and project cars. 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 4 series perfectly.
