[Land-speed] Fw: sway bar

[neil at dbelltech.com]

Tom;

A "sway bar" is an anti- roll bar-- it increases the roll stiffness of the
end of the car that it is mounted on. If you have a car with very stiff
springs and little suspension travel the anti- roll bar probably won't be
worth adding.

On a "normal" car the anti- roll bar is used to tune the handling of the
car; it makes a big difference whether the bar is mounted on the front or
rear.

I wouldn't use the bump stops as a rule-- when the suspension hits the
stops, the spring rate suddenly goes way up and this can upset things
dramatically.

Regards, Neil   Tucson, AZ
