im with a cage but theres state laws and they can cause some really bad blind spots but for the road seam welding and some strut braces do pretty good as well. if you wanna do it ur self get some good practise with a Stick welder then get skills with a MIG (don't use a gas-less mig) and if u can get a TIG welder

This is sort of true - If the only absorbtion you have is in the frame (no suspension or stiff suspension) then this is true. If suspension is present to help the tires stay in contact with the road then it's not quite the case.

Any frame/chassis must absorb torsinoal forces that are introduced during cornering and even during level driving on a less than glassy-smooth road. A frame can absorb these forces either by deflecting and twisting, like frame rails, or the members of the structure themselves can absorb the forces. The latter of thesem two methods makes for much more acurate location of the suspension, whereas the former allows the suspeision points (ideally set points in space) to move around.

Trucks intended to bear heavy loads are designed with little handling capability in mind. Leaf springs provide little to no lateral support, but are very durable under vertical load. The opposite is true of most car suspensions - good under lateral load but poor under vertical load.

"Chassis Engineering" is probably one of the best books you'll find explaining forces in race cars and what is needed for optimal handling and why - I would highly reccomend it.
