Editing Anti-roll bar (section)

===Adjustable bars===
[[File:Antiroll Bar2.svg|thumb|Diagram of two types of adjustable antiroll bars.]]
Some anti-roll bars, particularly those intended for use in [[auto racing]], are externally adjustable while the car is in the pit, whereas some systems can be adjusted in real time by the driver from inside the car, such as in [[Super GT]]. This allows the stiffness to be altered, for example by increasing or reducing the length of the lever arms on some systems, or by rotating a flat lever arm from a stiff edge-on position to a more flexible flat-side-on position on other systems. This lets a mechanic tune the roll stiffness for different situations without replacing the entire bar.
