Four-Link Suspension

Start / Calculations / Suspension Calculations / Four-Link Suspension

The 4-Link suspension simulation determines suspension geometry and anti-squat percentage based on these inputs:

Ground Clearance

Wheelbase

CG height is only used to calculate the anti-squat geometry.

Front tire diameter

Rear tire diameter

Front wheel diameter

Rear wheel diameter

Bump travel

Droop travel

Beneath the inputs is a diagram of the car. Each hole position is indicated by a yellow plus sign. The suspension links are indicated by blue lines. The instant center is shown with a blue plus sign.

Drag the car up and down and side to side to change suspension travel and rake angle (dive and squat). Stretch or pinch with two fingers to zoom. Touch the car to reset it to ride height position. A long touch will also reset zoom.

Select the desired hole position for each end of each link. The holes are listed by their vertical position.
