Do roll bars stiffen the chassis?

[rascal]

Engineers go to a decent amount of trouble to incorporate a certain amount of flex to prevent other parts while designing cars

No decent engineer would ever deliberately design in flex. They may accept some flex, as too expensive/heavy/impractical to remove it totally but that's totally different to designing it in in the first place..

Suspension working perfectly? No such thing. Only compromise.

Exactly. What's perfect for one is crap to another. Even top race drivers in same car prefer different set ups. It's completely impossible to engineer a car to suit everyone, so only ever a compromise. Hence ... we mod ......
