Chassis Stiffness

Hydro formed tubes are not readily available. They are made for specific purposes. A normal tube will work just as well for the mentioned purpose as hydro formed tubes.

Since the topic is live again,

Is there anyway for a owner to know till when does the stiffness be intact if properly maintained?

Are there any pointers or methods to check the flex in chassis?

These days I feel that my 2001 Vtec has become "loose".
Perhaps it is because of suspension, or perhaps because of the discussion in this thread = chassis flex.

How does one go about tightening the nuts?

How does crash-worthiness of cars, change with age? Does repeated flex, weaken crumple zones or passenger cell? Or is the effect negligible? Rust would definitely mess things, but I want to know results of "metal fatigue" (if I may call it that) over long durations like decades.
