Author Topic:   How do trailing arm lengths affect handling?

On asphalt at least that makes for rear steer. Because as the body rolls the axle will move fore/aft because of the arc of the trailing arms.

The right is typically run a degree or two more angle to create a little rear steer. I really don't know the advantages and disadvantages on the dirt though.

the shorter bars do react fast and can be made to work but on a rough track they are very erratic. You have to be smooth tomake them work.

Changing the length will change how fast they react..longer=slower, shorter=faster. Also by putting downward angle in them whether short or long as the car drives forward these bars try to push up on the chassis and this creates downforce on the tire giving traction. This is the big advantage of the short bars. They change angle faster under body roll and help create traction. Much like a 4link will. They also can create more roll steer which can help in certain situation but it can also cause problems though so you have to find a balance.
Racing is about compromise.. find something that works for you.
