Thanks for all of the questions & concerns about our chassis, & thanks MexMan for some clarification.
Like Rt 66 stated, our chassis bolts to stock locations in the front, but connects the front & rear sections together stronger than subframe connectors can do which makes it much stronger than anything else. To further triangulate the structure, we do supply firewall braces from the shock hoops to the firewall. Adding a rollbar is effective & can be tied to the chassis too.
Our frame does bolt-in, & doesn't require any floor cutting, & the frame can be removed if an owner wanted to (for some reason) convert the car back to stock.
