From the developer:
AeroSusp is for use by designers creating suspension systems from scratch and by race engineers tuning existing systems. It is based on mature code that has been in widespread use in top level race teams in many categories for over 15 years.
AeroSusp has been carefully designed from the start to avoid the pitfalls of over-complicated user interface design that other suspension design products have fallen into.
