Difference between Sway Bar and Stress Bar?

[team_v]

Please excuse my ignorance here, but is there a difference between the "Sway bar" you speak of, and the "Stress Bar" that this guy has installed in his boot of his Tig?

If they are different could someone explain the pro's and cons of each option?

From memory, a sway bar links both suspension members in order to reduce body roll and improve cornering through the linked suspension.

A stress bar is a cheaper alternative which bolts into interior body of the car and increases rigidity of the car reducing body roll to some extent.

For performance use, the sway bar is a much better alternative.

A sway bar (also stabilizer bar, anti-sway bar, roll bar, or anti-roll bar, ARB) is an automobile suspension device. It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns, independent of its spring rate in the vertical direction.

ABD Racing Stress Bars are all geometrically designed for each chassis. All chassis are not created equal and all require a different approach in reducing give in the body. The twin tube design proves to be the best design to eliminate any flex or twisting during hard driving.
