Take the time to inspect how the 'cage is attached to the framerails. On a Street Stock where the 'cage often must be welded to sheetmetal, there should always be a large metal plate welded between the end of the tubing and the sheetmetal to keep it from ripping off. And even on a purpose-built race chassis like this, the ends of the tubing should never be simply welded to the framerails. Leavitt says he's seen the tubing be ripped right off the framerails in a hard hit-even if they were welded properly. By adding a gusset wherever a part of the 'cage connects to the framerail, he can significantly increase the surface area of the weld-and the strength of the connection between the 'cage and the frame.
