Whether you're trying to find the right replacement springs for a restoration or considering modifying your car’s suspension to improve its aesthetics and/or cornering, this brief overview of a few coil-spring-related terms can help.

However, just because this article focuses on coil springs, it doesn’t mean that better handing begins and ends with swapping in a stiffer and/or lower set. Your car may react favorably to other upgrades before having to change the springs. Suspensions, as well as steering and braking systems, and wheel/tire packages, are developed by automakers to work together to meet specific goals. If you make too drastic a change with new springs or any other parts, it can have a negative effect instead of the intended positive one.

Since myriad chassis pieces influence ride and handling, the performance aftermarket normally provides upgraded springs as part of a package with matching additional components to ensure balanced improvements and safe operation. Speaking of the latter, never modify a suspension that has worn parts, or any that may not be compatible with the enhancements. Also, always use a coil spring compressor and adhere to all other safety measures. Find more coil spring insights...
