The answer is simple; you get what you pay for when it comes to vehicle suspension. As such a crucial component of your vehicle, suspension is definitely something you do not want to cheap out on. A coilover suspension basically gives you a matched lowering spring and shock absorber combination with the added benefit of adjustable ride height and spring rates through a moveable spring perch or perches. Coilovers are to your car's advantage by reducing unsprung mass, increasing suspension travel, and allowing the car to be corner balanced.
You may want to check out the ST V1 coilovers if your on a budget. Coming from the makers of KW suspension systems the only main difference between the ST Variant 1 and KW Variant 1 is the steel they use. While KW uses Stainless Steel for their shock housing, ST uses Galvanized Steel. However, this does not mean a drop in quality, durability, or appearance. Although coilovers that use galvanized steel are more prone to corrosion due to environmental influences (i.e. mixture of salt water); those in the lower states: California, Texas, Florida, Nevada, etc. don't have to worry about corrosion. Those in the mid to upper States that snow still don't have much to worry about as long as they do not drive in heavy snow conditions upon where salt is used on roads. To further ensure those with doubt about Galvanized Steel, ST has corrosion resistant zinc plating on all of their threaded strut housings for further protection. They're significantly cheaper than the KW lineup and are a popular choice!
