Lowering Springs Installation at ACG
The key component to making your car look its best.

 

We can install any type of aftermarket springs on your street or a track vehicle.

When on a budget, lowering springs is a great choice to make the car look and handle better. The most commonly used products are made by H&R, Eibach, Swift & Tien. There are other springs that may be worthy of research; however, the above-mentioned brands seem to be the most popular and are considered by most users to be most appealing, inexpensive, and fairly strut friendly when used with the OEM struts.

Each brand lowers the car differently so check out the specifications with the manufacturer's web site in order to make the right spring choice:

About Lowering Springs:

When upgrading your springs, you will most likely get a "Progressive Spring". This refers to the way a lowering spring is wound. The image below compares a standard OEM spring with a Progressive aftermarket spring.

The rule is that increasing the number of coils will decrease the stiffness of the spring. As you can see the aftermarket spring is wound tighter in at the top and the bottom and has less coils in the middle. This design makes the tighter-wound coils absorb most of the smaller road dips and imperfections making your regular street driving comfortable. When the car goes over a larger dip or goes into an apex of a turn at a track, the top and the bottom of a progressive spring will compress completely. At that time the middle of the spring with fewer coils will start taking the full load, taking your car through the turn.

On a specific vehicle, your average aftermarket progressive lowering spring would contain the same amount of coils as an OEM spring. A progressive spring is wound differently and that is why it is shorter then OEM. Because the amount of coils stays the same with an aftermarket spring, your car's shocks will not be overly strained. Invariably, this is why we do not recommend cutting OEM springs in order to lower your car. Not only it puts tremendous pressure on the shocks and wears them out quickly, it also destroys the ride quality and fine handling characteristics of your vehicle.
