AutoPower Industries is the number one producer of bolt-in roll bars and roll cages. A majority of their cages are compliant to SCCA and NASA rules. Using painted black tubing, their cages are designed to fit like OEM however require drilling into the frame for installation. Some configuration offer removal harness and diagonal bars as well as door bars. Vivid Racing has used their cages in several of our Project Cars from the Pepsi RX8, Porsche 996 Turbo, and our Nissan 240sx Drift Car.
