Thanks for the 411 on that mattMattyRattyPoo said:Firmware's design isn't a cage at all. They are just bars that are poweder coated and bolted on to the top part of the car and all the bends are crimped. Once that thing rolls or get in a bad accident, those bars are gonna snap and could possibly hurt someone. If you really want a cage, you need to gut you car and have a professional weld it in. Monster Fabrication is good as well as M1 Fabrication. Look to spend about $3000 for a custom rollcage thats welded and approved by all sactioning bodies of racing (not DOT apporved).
