Unsprung Weight Calculator

Professional Unsprung Weight Calculator for Race Cars Dave's Unsprung Calculator is a specialized tool designed by race car builder Dave Clark for calculating unsprung weight, spring rates, and ride frequencies on race cars equipped with dual-spring coilover setups. What It Does: This app helps you estimate your vehicle's unsprung weight using spring measurements and corner weight data. It's specifically designed for typical race setups with dual springs on a shock body with a coil carrier and slider mechanism. Key Calculations: • Total Spring Force - based on free length vs. ride height measurements • Bump Rate - single spring rate when the slider contacts the cancel-out nuts • Combined Rate - dual spring rate when both springs are active • Bump Frequency - natural frequency at bump rate • Combined Frequency - natural frequency at combined rate • Unsprung Weight - calculated from…
