Eibach springs are designed to improve the suspension of your vehicle. They will work with most coilovers and stock shocks to give you a better ride. The main advantage of Eibach springs is that they are made from high-quality materials and they're also adjustable. This means that you can fine-tune the spring rate to match your driving style and the conditions you'll be driving in.
It's important to note that all springs will settle over time, so it's normal for the performance of your Eibach springs to change slightly after a few thousand miles. However, the rate at which they settle will depend on how well they're made and how much stress they're under. In general, higher quality springs like Eibach's will settle less than cheaper ones.
If you're worried about your Eibach springs settling too much, there are a few things you can do to help them out. First, make sure that they're installed correctly and that all the hardware is tight. Second, don't use them in conditions where they'll be constantly under stress, such as off-road driving or racing. Third, check their condition regularly and replace them if necessary. By following these tips, you should be able to keep your Eibach springs in good shape for many years to come!
