There's actually only a few places in a roll cage that require gusseting. It's on the parts that are going to see torsion movement between the adjacent tubes. Most of the tubes in a roll cage actually are stressed in compression or tension as the car attempts to flex. And those cages are fully structural, not just safety. I think we are mostly concerned with a safety cage hre although I plan to incorporate a fully integrated structural cage into my coupe.

That blue car is a real piece of work. Originally built by BMW motorsport in Germany, it was run by Dieter Quester in the European GT series and I believe won the 24hrs Nurburging once plus the Spa Francorchamps endurance race before being sent to america. It eventually was bought by a team I used to work for in Jupiter and I'ver personally been through that car inside and out. The length to which BMW went in that cage construction is admirable.

We copied that cage design into another M3 we had and that car ended up being rolled on 2 seperate occasions. The car was still straight as an arrow on the frame jig!!! The first time it went over 2-1/2 times, the second time (first event after fixing the body damage and suspension) the customer/driver rolled it a good 4 rotations at Moroso. Needed a new roof but chassis was still intact. I was amazed.

Anyway, anyone interested in a serious cage for a great price should get in touch with www.Ter-tech.com in Palm Beach. They recently started working with Chassis Engineering in Riviera Beach to sell and install their weld-in cage kits and can do anything you could desire, from a 6-pt to a full integrated cage tied to the strut towers and rear subframe pickups.

Installed prices start at $700 including the cost of the tubes. Call them to set up a time and get a quote on the turn-around time.
