Understanding Coilover Stiffness
Coilover stiffness, often referred to as “spring rate,” is measured in pounds per inch (lb/in) or kilograms per millimeter (kg/mm) and represents the amount of force required to compress the coil spring by one inch or one millimeter, respectively. Stiffer coilovers have a higher rating, indicating that more force is needed to compress them.
This results in less body roll and more direct handling characteristics, which is appreciated in performance driving situations. On the other hand, a lower spring rate allows for more suspension travel, absorbing road imperfections for a smoother ride. Ultimately, coilover stiffness adjustment involves finding a balance between comfort and performance, taking into account the vehicle’s weight, intended use, and personal preference.
Preparing for Adjustment
Before adjusting the stiffness of your coilovers, it’s essential to prepare thoroughly to ensure safety and accuracy throughout the process.
