The process is not difficult, so anyone with garage access and a little know-how can accomplish this modification. Since lowering springs are designed to work with your existing factory suspension, they can simply replace your coil springs.

takes about 4-6 hours on the parking lot and 2-3 hours on the lift.

Lowering springs also change the geometry of your wheel/tire fitment. If it’s not done right, you can expect both accelerated and uneven tire wear. Your car could also bottom out over speed bumps and be even tougher to get up inclines, like your driveway, without scraping your bumper.

If you have to pay someone to do it though, $100 isn’t bad at all. After doing a couple spring installs myself now, I would personally be fine with paying someone around $200 to do the job if I didn’t know what I was doing.

Tools To Install Lowering Springs

1. Basic hand tools, including screwdrivers, pry bars, metric and fractional wrenches, metric and fractional sockets, ratchets, and extensions.
2. Impact wrench, either electric or pneumatic.
3. Floor jack and jack stands.
4. Spring compressors.

1. Jack up the rear of the car and put it on car stands.
2. Remove the rear wheels.
3. Remove the shock nuts and bolts. (You can locate them by referring to the owner’s manual.)
4. Remove the springs.
5. Install the new lowering springs.
6. Replace the shock nuts and bolts.
7. Replace the rear tires [source: Do It Yourself].

Myth 1: If I buy lowering springs, I can’t use my original shocks. Fact: Springs that produce mild lowering of about an inch work well with newer factory shocks. In fact, Eibach’s Pro-Kit Spring Set and even their more aggressive Sportline Spring Set are designed around a vehicle’s original suspension.

Okay everyone is missing the big picture here: Installing lowering springs is easy, but there are a lot of intricacies to it: -Suspension bolts tend to get locked on which may require some serious tools ie impact wrench to get through. A breaker bar often can do the job, but makes it a pain in the ass.

there has even been speculation that the warranties are voided if you look at the car on the showroom floor. ….. but yes lowering your springs will void your bouncing and cornering warrantee. changing any part on the car will void the warrantee for that part as well as any subsequent parts that it effects.

Poorly done or extreme lowering can cause suspension and steering parts to contact each other, the wheels or the tires. It could also cause tires to rub the body during turns or going over bumps.

Professional Services. The assistance of a professional will cost you a good deal as well. If you are paying $150 for your springs, then expect to see around the same cost again for the installation. This will include alignment, which can be the most difficult part of fitting the car, and also the tax costs of the work …

Long answer short, “YES”. Your OEM shocks will wear out quicker than normal if you install lowering springs. OEM shocks were not designed to sit lower with smaller springs.

Lowered vehicles are more aerodynamic. There’s less air hitting the wheels and tires (that are not streamlined shapes). This makes these cars faster. Some owners of low-stance vehicles also notice improved gas mileage.
