RX-7 Roll Cage

[jwesleyc3]

Thanks for the advice forum members. I am going to order an Autopower U-Weld cage along with the race roll bar and go from there. There cages are legal in the SCCA so I am settling for this. I found these guys in back of an old Grassroots magazine.
Thanks again for the quick replies.

Some gneral comments:

1- DO NOT buy a cage designed for another car. period. It will be HARDER than starting from straight tubes.

2- A custom cage often is safer, roomier and in the long run better than a pre bent one.

3- Thick/heavy tubes are only one indication of safety...design is as, or more important.

Remember in high school when you had to build that bridge using only a certain number of balsa wood sticks?

4- If you go the pre bent route, consider gusseting and extra triangulation. Often this requires no bending, but adds significant strength. Remember, triangulation is key, and give loads a route to follow. Also, attach the downtubes to multiple and vertical sections whenever possible.
