Q: How far can I safely lower my car?
A: Most cars can be lowered 30 mm without any detrimental effect. This
reduction in height will usually allow the car to remain within good
engineering and roadworthy parameters. In some special cases, it is
possible to lower further but expert advice should be obtained before
doing so. Substantial lowering is a popular fashion but it is often
a very bad idea. Many cars, if fitted with very low springs will sit
on the bump stops, and the suspension will not move. This can be both
dangerous, and destructive to various components. KONI'S
are designed to fit standard height cars, but can work equally well
on lowered cars as long as they do not "bottom out". The shock
absorber and suspension components generally must be protected from
harsh bottoming by the factory fitted bump stops. These should not be
removed or shortened. Contact
Toperformance for advice.
Q: KONI makes some
shocks that are not gas shocks. Why?
A: There are basically three types of shock absorber designs: Mono-tube
high pressure gas, Twin-tube low pressure gas, and Twin-tube hydraulic
(non gas). Each of these designs has certain ride and performance characteristics
that can enhance the performance of a vehicle. KONI
produces all three designs. KONI ride development
engineers evaluate each new vehicle and then decide which shock design
would best apply to that vehicle. Some cars respond best to mono-tubes,
some like gas pressurised and others don't.
Q : What is the
difference between KONI Special (red) and
KONI Sport (yellow)?
A: The Koni Special (red) has been designed
to provide the best all round ride quality and handling combination.
The Koni Sport (yellow) damper is designed
for overtly sporting style driving. This damper has increased
compression and rebound damping when compared to the Koni
Special. Many Sport dampers are externally adjustable.
In many applications, Koni offer both a
Special, and a Sport version. In other applications only one type
of damper is available. Some modern cars are supplied by the manufacturer
with a sports style suspension, so the appropriate Koni damper to use,
is the Sport version. However the Koni Sport
is still valuable in optimizing the ride/handling qualities of the car.
Q: How does KONI damping compare to factory
A: This is a difficult question to answer because every KONI
application is developed for that specific vehicle to get the best ride
and handling characteristics. In general, most factory shocks are under
damped for optimised handling so KONI engineers
select firmer valvings. Unfortunately factory shocks are generally chosen
for financial reason rather than performance so lower technology, cheaper
shocks are the standard. In some instances, a factory shock may have
good charateristics in some parts of the working range, but need some
help in other parts. There are even a few instances where KONI engineers
have found better handling by valving softer than the factory units.
Q: What is the best setting for my KONI's?
A: The adjustment is provided principally as a
life extending mechanism. Do not over adjust.
For most vehicles, we suggest you fit the Koni's
as they come, that is, in the full soft setting. This then will provide
the best combination of ride and handling as designed by
Koni suspension engineers. There may be some vehicles which require
special consideration in regard to the adjustment. For example, 4WDrives
that frequently carry heavy loads, cars that owners prefer to be more
sporting in character or cars that have firmer springs installed.
If adjustment is required, one half turn, up to one and one quarter
is the maximum amount usually applied. (one click on the mono-tube type).
Do not use force when a stop is felt.
Q: Do I need to change the springs in my car?
A: Koni's are always designed to
work with the original springs and suspension settings in mind, as they
are the very best replacement shock absorber you can choose. Generally,
springs do not need to be replaced as they rarely cause any problems.
If however, the springs have obviously sagged excessively or if you
would like to have higher rate sports springs, Koni's
will continue to be the best choice, as they can be adjusted
through a simple process to provide the rebound damping that will be
required with the firmer springs. Shock absorbers are heat exchangers
that absorb the energy stored in the spring, convert it to heat which
is dissipated through cooling. If the energy is not dissipated
adequately, the car will ride and handle poorly. While full adjustment
will double the rebound rate, after-market springs will require only
a moderate change to the adjustment. Koni's
very rarely require full adjustment. Fitting sport springs with old
worn dampers is a bad idea, which will result in a harsh, uncomfortable,
bad handling car.
