About the application:

Speed-Wiz Four-Link Pro has all the four-link suspension calculations you need to build and set up four-link suspensions for vehicles and trucks. It's simple to enter your four-link suspension info. Any number of holes can be specified for each end of each link. Then it's just one touch to switch from one to other and immediately visualize the suspension geometry. The vehicle profile view shows the suspension link positions as the vehicle travels up and down and dives and squats. You simply drag the vehicle around to view your four-link suspension geometry changes.Please note: Vehicle Math Pro is replacing this app.Four-link suspension calculations:- 4-Link simulation- 4-Link hole definitionFour-link suspension graphing:- 4-link centers: graph X and Y positions of instant centers for all combinations of holes- 4-link holes: illustrates X and Y positions of all holes- 4-link travel: shows instant center X and Y place curves for over suspension travel- 4-link rake: shows X and Y place of instant center over squat and dive changesEasy and fun to use with sliding menus and swipe viewsMakes setting up your 4-link suspension a pleasureAutomatic, instantaneous simulations and graphsAccurate, reliable, and proven algorithmsUnlimited car data and configuration filesContext-based online helpMetric and English inputs and outputs with automatic conversionNo advertisingOther Speed-Wiz vehicle math modules contain Engine Pro, Chassis Pro, Tire Pro, Brake Pro, Performance Pro, Suspension Pro, Turbo Pro and more!
