– Why Is Spring Brand Important? –

In a word: Accuracy. Low quality springs tend to have a lot of rate distortion. If you have a 7k spring and you hit a pothole even though the spring is supposed to be linear and stay close to 7k throughout the range of compression it will often jump up by 20% or more which is very bad for ride quality. It’s also not good for consistency when you’re cornering. Low quality springs often don’t match the rate printed on the side. A 10k spring might actually be closer to 8k or 12k. One supposedly identical spring might not match the next. This is obviously not good for handling. The car may not feel the same when you are turning left as when you are turning right. You may have different amounts of understeer or oversteer than you desire, and the overall neutrality of the car could end up being pretty inconsistent. Low quality springs also tend to sag and change over time. This means you lose preload, ride height changes and rate likely changes as well. A spring may seem like a simple part because it’s just a piece of steel, but as you can see it’s a very important piece of steel. After the damper this is the most important component of your entire suspension.

The most accurate springs that we have experienced after 16 years of custom coilover builds and running hundreds of springs through rate testers are not 100% perfect, but they are massively better than the entry level springs that come on most coilover brands. They are much more linear, they have very little distortion, and they typically don’t sag, settle or change rate over time. This will have an extremely positive impact on both ride quality and handling. If your springs are not working properly the rest of your suspension does not matter. We always highly encourage people to upgrade their springs if it’s within their budget.
