Lowering springs are special aftermarket springs that you can buy to replace the stock springs that were installed when your car was manufactured. Lowering springs are a little shorter with more coils than stock strings, which means they create more tension between the suspension system and the frame, causing the body of the car to rest further down, closer to the wheels. This lowers the vehicle's center of gravity, making it easier to handle, and also gives it a stylish, "low rider" appearance.
What Lowering Springs to Buy
Before you set out to buy lowering springs, you have to make sure you know what kind you want to get. You don't want the lowering springs you buy to be too strong, because your car may sit too low on its suspension. To make sure that you don't buy springs that are too strong, measure the distance between the top of your car's tire and the top of its wheel well. Any spring that advertises lowering greater than this distance will be unsuitable. Just in case, tack on an additional inch to your measurement as a margin for error.
Where to Buy Lowering Springs
There are many online organizations that will sell you lowering springs made by various aftermarket auto part manufacturing companies, and you can also probably find lowering springs for sale at any auto body or department store. The most popular companies that make lowering springs are Eibach and H&R. Both Eibach springs and H&R springs come in various strengths, so you are likely to find one that is right for your needs.
How to Install Lowering Springs
The process of installing lowering springs is rather complicated, and you should only do it if you have experience taking cars apart and putting them back together. Since you have to take apart the whole suspension system, it is recommended that you take this opportunity to change the shock absorbers in your car as well. Jack the car up and get it on jack stands so you can work with the suspension without the car falling on you. Remove the wheel and the shock bolt from the corner of the car you are working on, which will let the suspension drop enough for the spring to be removed. Use a spring compressor to hold the lowering spring so it can be installed, then carefully remove the compressor once the spring is in place. Repeat this process for all four wheels of the vehicle.
Although lowering springs are a great way for you to improve the handling of your car as well as give it a cool new appearance, the process of changing the springs in a car is complicated to do yourself and expensive to pay a professional to do. Lowering springs are not at all necessary for your car to function properly, so you should only get them if you are willing to put some serious money and effort into your vehicle.
