Installing a set of BMW 3 Series coilovers will give your ride a whole new level of performance and suspension adjustability reserved in the past for only high end race cars. The ability to corner balance and fine-tune your suspension with various settings for different road and track conditions will give you a new appreciation for what your ride is capable of, especially during cornering. When trying to choose between your different BMW 3 Series coilover options, keep in mind that the more established (and often more expensive brands) have much more research, engineering, and track testing behind them, and are valved specifically to work best with your particular vehicle.

If you are building a high-performance vehicle or a show car, a lowered suspension is a must-have modification. However, many full coilover kits are prohibitively expensive. But that doesn't mean that you have sacrifice performance with cut springs; BMW 3 Series coilover sleeves offer many of the benefits of a full coilover at a fraction of the cost. With aftermarket BMW 3 Series coilover sleeves you add a tunable spring perch to your OEM shocks to give you full ride height adjustability. Here at Andy's Auto Sport we have an excellent selection of BMW 3 Series coilover sleeves for you to select from. This is the perfect modification for the budget minded enthusiast.

Most coilovers are adjustable for height and damping, and a select few feature threaded shock bodies that allow ride height to be adjusted separately from the coil spring adjustment, which lets you dial in your spring preload for the ultimate in suspension tuning. You can even swap out your BMW 3 Series coilover springs with other springs of various rates to adjust your ride quality and stiffness. Coilovers with adjustable damping sometimes have up to 32 levels (sometimes referred to as "clicks"), although most enthusiasts will skip a click since the difference from one level to the next can be very minute.

Suspension tuning is a crucial element of maximizing your vehicle's performance. Unfortunately not all driving surfaces require the same suspension setup. Perhaps the biggest advantage of BMW 3 Series coilover sleeves is their adjustability. Thanks to a threaded spring perch design, the simple twist of a wrench can raise or lower your suspension depending on whether you are tacking pot-hole riddled streets or are about to hit the glassy smooth race track. In addition coilover sleeves use standard sized coilover springs so it is easy to swap spring rates and your choice of springs are seemingly endless. This is one of the best suspension upgrades you can make.

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: 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.

Q: Do coilovers come in sets of 4?
A: Coilovers are only sold in sets of four.

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: 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.
