Q: How do you install coilovers?
A: Depending if you opt to go with the full coilover systems or the coilover sleeves, the spring and strut housing will need to be removed. Once the factory coil springs and struts are removed they can be replaced with the full coilover setup. If you're using a coilover sleeve then the factory spring will be removed from the strut setup and replaced with the coilover sleeve unit. A professional shop should install your coilovers as an alignment and corner-balancing services will need to be done at the same time the installation is completed.
Q: Do coilovers come in sets of 4?
A: Coilovers are only sold in sets of four.
Q: Will I need a camber kit after installing coilovers?
A: In some cases you will not need a camber kit, as long as your local alignment can be put back into proper specifications. If not, a camber kit will help by allowing additional adjustment beyond what your factory alignment parts are capable of.
Q: What do coilovers do? Why buy coilovers?
A: Coilovers allow you to lower your car and give you the ability to make adjustments in ride height. As opposed to lowering springs, which have a pre-determined, un-changing ride height, coilovers can be adjusted. This can be very valuable because if you don't know the exact ride height that will be optimal for your car, buying coilovers gives you the ability to adjust the right height and make it just right. Additionally, if you want to change your ride height based on different driving conditions, coilovers of course allow you to do so.
Q: Why is there such a huge price difference between some coilovers? Are there different types of coilovers?
A: There are two different kinds of coilovers: full coilover systems and coilover sleeves. Coilover sleeves are just the adjustable coils themselves. If you already have shocks or struts and have a camber kit that you're content with, then just buying the coilover sleeves will be adequate. Also, if you are looking for adjustable lowering components that are inexpensive, coilover sleeves are the way to go. Full coilover systems on the other hand come with not only the adjustable coils, but also with replacement shocks or struts and with a built-in camber adjuster. Full coilover systems let you drop your car and maintain or improve ride quality, and maintain even camber. The shocks that are built into full coilovers are specifically made for lowered cars, so they will ensure a great ride quality.
