There is not much to say about sway bars! Nevertheless, it is important enough to write a special lesson for this part because with different sway bars you are able to change the behavior of your truck. So let us start!
First, you need to know on which type of track or field you are going to drive with your Losi. In all previous lessons you have learned that this is the most important thing to choose your setup. With sway bars, it is not any different. In the next chapters, we will explain the thicknesses, also referred to the diameter of the wire, of sway bars and the effects on the handling of your car.
2. Front Sway Bar
The standard sway bar on a Losi 5ive-T and 5ive Mini WRC RTR in front is 3.5mm. There is an upgrade part from Losi available (part number LOSB2562), which includes different thicknesses. Installing a thinner sway bar increases the traction off power, but has less on power steering. A thicker sway bar decreases off power traction with smoothing steering into the corners, but it has more on power steering. So a thinner sway bar on small and bumpy tracks with tight turns while using a thicker sway bar while driving on an open field or large track.
3. Rear Sway Bar
Just like the front sway bar, the Losi has a standard 3.5mm installed on the rear of the car. Using a thinner rear sway bar increases rear traction and reduces on power steering. A thicker rear sway bar increases stability into the corners and improves on power steering. So installing a thicker rear sway bar while driving on a large and high traction track is a good choice.
4. Tuning Sway Bars
Another important item to keep in mind with sway bars is how loose or tight they are in the sway bar mounts. There are small setscrews that allow you to adjust the play of the sway bar. Having the setscrews loose allows the sway bar to have “play”, which will allow the vehicle to be less sensitive and easier to drive on bumpy tracks. Having the setscrews tighter, therefore having less “play”, will provide a more responsive vehicle and may result in not handling bumpy conditions as well. Always keep in mind that you never want to fully tighten the setscrews onto the sway bars. With the links disconnected, (link from suspension arm to sway bar ball) the sway bar should always be free allowing a free suspension system.
