Description
If you’re building a coil-over suspension system or tuning an existing setup, spring rate selection directly impacts your vehicle’s handling balance, ride quality, and track performance. The QA1 10HT100B delivers a moderate 100 lb/in rate that works across a wide range of applications—from street-driven performance cars to amateur track builds—without requiring extreme damper tuning or compromising comfort. Its compact 2.5-inch inner diameter and 10-inch length integrate seamlessly into most modern coil-over platforms, giving you the precision spring rate you need to dial in your setup.
