This bolt-in roll cage / half cage solution for the G82 M4 and G22 4 Series Coupe chassis exhibits both form and function. StudioRSR developed an outstanding roll bar solution that can be used in motorsport, HPDE, drag race, and track-day needs. The Tesseract cage increases both chassis rigidity and safety, while offering a modern design worthy of a BMW M4 or Premium BMW 4 Series Coupe. We consider the StudioRSR Tesseract roll cage the premium option for this application. 

StudioRSR both designed and manufactures this solution in house, using modern manufacturing technology to create an upgrade with wide-radius bends, required for NASA Racing specifications**. The end result is a NO metal crimping, no tube deformation, and no tubing wall failure, which is an ugly aspect of many competing roll bars on the market. 

100% Bolt-in Solution
The Tesseract half-cage is a true bolt-in half cage, with an optimum 4-point mounting design and form-fitted brackets SPECIFIC to the G22/G82 coupe chassis. This isn't a "one size fits most" rollbar, but a specifically designed for for the 2021+ G82 M4 Coupe, and fully compatible with the 2021+ 4 Series Coupe (430i & M440i) as well. Installing this roll bar does require removing the rear seat back, which has weight reduction value on its own. 

Professional installation is always recommended, but installation is made easy with Studio RSR's proprietary chromoly interlocking tubing clamps. This means ZERO welding! All necessary hardware is included, as well as installation instructions. Thanks to this two-piece interlocking construction, this roll bar solution can be shipped directly to you, or your installer's doorstep. 

Studio RSR developed a strong track/enthusiast clientele starting with previous generation M cars, such as the E36, E46, E9X, and -- the predecessors to the G82 M4 / 4 Series platform. They leveraged the experience from NASA & SCCA Racing, HPDE, and time trial classes to create a truly professional motorsport solution. The Tesseract's visual aesthetic matches the aggressive, modern design of the BMW G22 / G82 M4 perfectly.

Shipping / Freight / Delivery Lead Time
Due to the large / bulky / heavy nature of roll bars, this must be shipping via common carrier freight. Freight within the lower 48 states is ~$200 and shown during checkout. Expedited freight is NOT available, and is subject to both the lead-time to build your roll bar, as well as for the trucking transit time to deliver. We can not deliver roll bars with guaranteed delivery because of this. Please order early and accordingly.
