Hey guys, this is a car TRM designed and installed the cage for. It was installed months ago, and has garnered some serious praise from tech inspectors and racers alike since its owner's racing debut in August.
It's a bit more expensive than most people are paying for cages that are just fabricated, but having a cage that's engineered is worth it to a lot of racers. (bolded for an important distinction) Of course a well engineered design can't make up for crappy craftsmanship, but this cage is certainly one of the most well built as well.
I've also edited in some comments to distinguish this cage from some others we've seen around that contain some not-so-awesome features.
Note how the dash bar runs behind the dash and steering wheel... far above the driver's knees. (Here is a different cage for comparison. Note the dash bar location, just because they were too lazy to remove the dash to install the cage.)


Of course all the welds are neat and tidy, made in one pass with a properly sized welder. (Lots of cages are done with smaller 115V welders that don't have the juice to weld .095 tube in one pass.)

Check out the close fit to the B-pillar. (Comparison here) Obviously closer to the chassis means farther from the driver, which makes a tight fitting cage safer.

Foot protection is an optional extra on a lot of cages. By the way, I've also seen cage fabricators weld in tubes with the wiring stuck behind them, which I think is pretty hilarious.

This is a node: a point where multiple tubes meet. This allows loads to be transmitted along the length of the tube to compress it instead of bending it. (Compare that to this cage, with poor nodes. (Tubes don't all meet at the same point.)

Custom roll bars (from the main hoop back) are also available, installed only at this point but we're thinking about coming out with a weld in kit for the roll bars. Cages can also be built to any class rules and customized for driver size and car setup (rear coilover reinforcement for example) on a one-off basis.
Thanks for looking!
