Details:

With regards to undercar chassis bracing, Whiteline engineers have tested and identified up to 15mm body flex on late model vehicles under moderate acceleration, braking and cornering loads. Chassis bracing maintains alignment angles and spring rates by greatly reducing body or chassis flex. In fact, it helps every component in the suspension system do its job properly. Race cars have elaborate roll cages not just to protect the occupant, a good proportion of its job is to stiffen the chassis. That’s why it triangulates and links every major chassis and suspension pickup point with each other. Critical for serious performance and essential for any car with uprated springs, shocks or swaybars.
