Four-Link Pro for PC

Speed-Wiz Four-Link Pro has all the four-link suspension calculations you need to build and set up four-link suspensions for cars and trucks. It's easy to enter your four-link suspension details. Any number of holes can be specified for each end of each link. Then it's just one touch to switch from one to another and immediately visualize the suspension geometry. The car profile view shows the suspension link positions as the car travels up and down and dives and squats. You simply drag the car around to view your four-link suspension geometry changes.
