Swaybar - Anti Roll Bar - Anti Swaybar - Stabalizer Bar --

This is a wire or blade that connects the left and right suspension arms of a model and hinges on the chassis. Swaybars reduce body roll and create a smoother load transfer from one side of the model to the other while cornering. Swaybars may be used on off road or on road models, and may be used on the front suspension, rear suspension, or both. There are two basic types of swaybars - wire and blade. Wire swaybars are the most common (and the only type used on off road models). They are basically formed spring steel wire that twists to create tension. A thicker wire = a stiffer swaybar, while a thinner wire = a softer swaybar (a.k.a. swaybar rate). Blade swaybars are machined pieces (usually machined from spring steel) that resemble a flat leaf spring. Blade swaybars are used with on road models (almost exclusively 1:8 scale on road), and flex to create tension. As with wire swaybars, a thicker blade = a stiffer swaybar, while a thinner blade = a softer swaybar. In general, swaybar rate should match shock spring rate - stiffer swaybars with stiffer springs, and softer swaybars with softer springs. The following represents basic swaybar tuning:

- FRONT (STIFFER SWAYBAR) - This is good for twisty tracks with a high bite surface. A stiffer front swaybar increases rear traction and steering response while cornering, but reduces front traction and off power steering. Great for increasing corner exit speeds.

- FRONT (SOFTER SWAYBAR) - A softer front swaybar (or a rear swaybar with no front swaybar) increases turn in while braking, but reduces rear traction and steering response. Great for overtaking while entering corners by allowing late, hard braking.

- REAR (STIFFER SWAYBAR) - This is good for tracks with long sweepers and a medium to high bite surface. A stiffer rear swaybar increases front traction and steering response, but decreases rear traction. Great for passing on long, high speed corners.

- REAR (SOFTER SWAYBAR) - This is good for low bite (loose or loamy) tracks. A softer rear swaybar (or a front swaybar with no rear swaybar) increases rear traction and reduces oversteer. Great for increasing corner speed and helping to prevent spin outs.
