AIR SUSPENSION FREQUENTLY ASKED QUESTIONS 2
How do I adjust my ride height?
The ride height on the majority of our coilovers is designed to be adjusted through the lower mount,
NOT by turning the spring perch. The lower mounts are installed on the bottom of the threaded shock
body. As you spin the lower mount further onto the shock body, you are shortening the overall length
of the entire coilover assembly, which results in a lowered vehicle ride height. Once you have turned
the lower mount to your desired setting, tighten the locking collar against it to lock your settings in
place. To raise your car, twist the lower mount counterclockwise making the overall length of the
coilover longer, thus resulting in a higher ride height. For safety reasons, always make sure at least 30%
of the lower mount is threaded onto the shock body.
This design is extremely benefcial to performance enthusiasts and those looking to get the most out of
their suspension tuning as it allows you to raise and lower your vehicle without interfering with the
shock’s compression or travel characteristics.
Certain applications are not designed to have an adjustable lower mount and are raised or lowered by
adjusting the spring perch. In most cases, a helper spring is present to ensure proper adjustability
without sacrifcing ride quality. To adjust the ride height, lower the spring perch assembly by twisting it
counterclockwise and giving the assembly more room to compress, resulting in a lowered ride height.
How do I adjust the 36-way damping on my coilovers?
All Best Racing coilovers feature 36-way damping adjustable shocks which allow you to fne tune them to
your specifcations. For coilovers that feature non-inverted shocks, the damping can be adjusted at the
top of the coilover assembly. For coilovers featuring inverted shock assemblies, the damping settings
can be adjusted from the bottom of the coilover. To adjust, insert the provided damping adjustment
knob and turn it left or right to adjust from H (Hard) to S (Soft). You will feel the knob “click” with each
turn, indicating one step up or down the 36-way adjustable range.
How do I preload the springs on my coilovers?
The springs on your full coilover should already be preloaded out of the box (Always verify this prior to
installation). The spring itself should be snug up against the top of the coilover and the locking perches
at the bottom should be snug up against the bottom of the spring. The spring should not have any free
play or be able to move up or down. Do not crank down on the spring and cause it to compress as this
can result in unpleasant ride quality.
Why don’t my coilovers have camber plates at the top?
Only cars with MacPherson style suspension are designed to have camber plates accessible at the top
of the coilover. On most other non-MacPherson style applications, the camber should be adjusted through
the use of a separate upper or lower camber kit.
Will I lose shock travel by lowering my car?
No. Our coilovers feature a fully adjustable lower mount which allows you to raise or lower your vehicle
without afecting the shock’s travel or compression characteristics. This design is very advantageous
over cheaper suspension kits which use the spring itself to adjust ride height, which can cause
premature shock failure and terrible ride quality.
How do I care for my coilovers?
We recommend to routinely inspect your coilovers as you would various other aspects of your vehicle.
It is especially important to inspect them and keep them clean if you live in climates that experience
heavy winters or rainfall. Over time, debris and dirt can accumulate on the coilover assembly and
threads which can cause problems in the future when you want to adjust them. If you feel your
coilovers need to be cleaned of, we recommend using a non-corrosive cleaning spray that can be
purchased in most auto parts stores.
I sometimes hear a clunking sound coming from my coilovers. What is that?
Coilovers for cars with McPherson style suspension have metal pillow ball bearing upper mounts. Due
to the metal on metal contact within the bearing, there is sometimes an audible noise that can be
heard. We recommend lubricating the pillow ball mount with the included bearing grease or a noncorrosive penetrating lubricant when you first install the coilovers
