Roll Bars & Cages

03-08 BMW Z4 Hardtop

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.

Images on this page are not vehicle specific. Actual shape will conform to the features of your vehicle.

PAINT FINISH Most steel products are sprayed with an industrial grade gloss black cover coat for rust protection. EXPECT some paint damage during shipping. You may want to refinish products before final installation. You must check fitment and drill all holes before you have the roll bar re painted, powder coated or any other finish added to the product. AUTOPOWER is not responsible for any cost of aftermarket coatings. There is no paint finish guarantee.
