Designed to quickly and easily transform your street car into a race legal competition car. This cage closely conforms to your car’s interior, allowing quick entry & exiting. It uses precision fit, 6 mounting point, slip-tube and bolt-in design.

This cage is approved by SCCA and NASA for open road racing and drifting events. The best fitting pre-fab cage you can buy.

Our roll bars and cages meet or exceed the safety requirements for most competition sanctioning organizations. Our bars and cages have been designed to easily install and provide maximum protection. The fit in your vehicle allows quick and easy entry and most importantly, quick exiting, while conforming closely to your interior for a clean, unobtrusive look and feel.

All of our bars and cages are certified MIG welded and precision jig notched, providing you with the maximum strength and best fit available. Every roll bar or cage has been designed to fit ­specific car models so only minor ­modifications are necessary for the instal­lation. Most applications are a true bolt-in and require NO WELDING.



  • SCCA & NASA legal for club racing.
  • Top of the line in fit and construction.
  • All cages are made to order, allowing for tube size and type to be selected.
  • Diagonal cross brace and horizontal brace are a permanent weld-in design.
