Description

SpringSpec is a specialist spring rate calculator for motorsport suspension, built by race engineers for race engineers. Enter your corner weights, unsprung mass, and motion ratio — SpringSpec calculates wheel frequency, wheel rate, critical damping, and static deflection across every standard spring rate. It then recommends Soft, Recommended, and Hard options based on your intended use and drivetrain layout, and matches you to real parts from the Eibach ERS and Hyperco catalogues. KEY FEATURES — Dual-axle calculator with frequency, wheel rate, damping and deflection for every common spring rate — Drivetrain-aware balance: front-engine RWD, mid/rear-engine RWD, FWD — Target presets from Road to Race (1.3 Hz to 2.2 Hz) plus custom entry — Motion ratio entered as a decimal, squared internally — the correct engineering convention — Colour-coded frequency bands (Road, Road/Track, Race, Too Hard) — Built-in catalogue lookup for Eibach ERS and Hyperco springs, filtered by rate, free length, ID, and travel — Motion Ratio Guide with clear diagrams and two measurement methods — Save customer jobs locally with full inputs, results, and notes — Works in lbs/in, N/mm, or kg/mm NO ACCOUNTS. NO CLOUD. NO ADS. NO SUBSCRIPTIONS. All your data stays on your device. One-off purchase, updates via the App Store. DISCLAIMER SpringSpec provides engineering guidance based on the data you enter. Always verify inputs and outputs independently. Suspension setup affects vehicle safety — verify all choices against manufacturer specifications and, where appropriate, a qualified motorsport engineer. Published by RaceTracs Ltd, United Kingdom.
