references _ Paved Track Stock Car Technology by Steve Smith Tune to Win by Carroll Smith Software - Suspension Analyzer by Performance Trends In order to understand the complexity of a Formula Cars suspension, a basic knowledge of the stock car suspension should first be mastered. When designing a (front) suspension , geometry layout is critical. spindle choice and dimensions, kingpin and steering inclination, wheel offset, frame height, car track width, camber change curve, static roll center height and location and roll axis location are major factors. The first critical thing to do is to establish the roll center height and lateral location. The roll center is established by fixed points and angles of the A-arms. These pivot points and angles also establish the camber gain and bump steer. I have used Suspension Analyzer for years on Super late Model stock cars as well as formula cars and it is as critical as a tire pyrometer and stop watch, in my opinion..Saves tons of time figuring the roll center and will show the roll center movement as the suspension moves through its travel.
