Cusco Roll Bars Explained

There seems to forever be a debate about Cusco roll bars and cages. They are often used in Japan, and as such, customers here want them for that reason alone. Secondly, they have a tremendously broad range of applications, so one is available for a ton of different cars. However, what many people don’t realize, is there are more than 1 type of roll bars and cages. Each has a specific purpose, a specific construction. With this entry, I hope to clear up some of the confusion, so people understand each one in a clearer way.

First up, you have the often-seen “Blue” rollbar and/or cage. This is called their D1 Spec. As you may have guessed, it is named as such because they are legal for use in the D1 Drift events. Granted, they are offered for a wide array of cars, and many of these cars will likely never drift. But this is what their design, manufacturing, material selection and mounting is geared towards. They also can be ordered in many other colors besides blue, but of course, for this part, that is the signature color. These are made of 40mm diameter chromoly, they bolt in, and are offered in 4 point through 8 point mounting.

Next up, are the Safety21 line of roll bars and cages. These differ significantly from the blue D1 spec units, in that they are made of 40mm cold drawn seamless carbon steel. They are available in 4-14 point in both bolt in and weld in mounting. The Safete21 units are used in Cusco’s GT300 efforts as well as in many of their club level rally cars. Some have FIA approval, depending on the number of points, and the application. These generally come finished in black, though again, custom colors are available. They have larger mounting and reinforcement plates vs the D1 spec units as well.

Lastly, you have Cusco’s ASN-FIA Spec cages.These are full Regulation J spec cages, weld in only, and used in WRC as well as GT class racing.
