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.
