Note: Minimum recommended travel: 3 in bump, 2 in droop for street cars. Bump stops should engage before coil bind. Droop limiters prevent over-extension.
Reference
Static Deflection = Corner Weight / Spring Rate
Loaded Length = Installed Length - Static Deflection
Bump Travel = Loaded Length - Coil Bind - 0.5" safety
Droop Travel = Preload + Static Deflection
Bump Force = Total Compression x Spring Rate
