makes Eibach springs better than others?
Eibach springs obtain their impressive
performance through an extensive process,
beginning with nearly 50 years of spring
technology by dedicated engineers, craftsmen
and enthusiasts. We take our years of racing
experience and combine them with controlling
every aspect of producing the finest
performance springs. This journey begins
with our own engineers extensively testing
and determining the optimal design
characteristics for each application. We
then manufacture the springs using spring
wire to Eibach engineers specifications on
computerized coiling equipment. We are
pleased to be able to have this question
best answered by our "very picky"
partners from around the globe who have
already discovered Eibach´s commitment to
quality, consistency and performance is
second to none. Thank you McLaren F1, AMG-Mercedes,
Audi, BMW, Ford, VW, Alfa, Lotus, Alpina,
Aston Martin, Porsche, Ferrari etc.
want to lower my car, but do not want to
give up my ride quality, will Eibach springs
ruin my ride characteristics? Index
Eibach engineers are familiar with the
balance of optimizing handling while
maintaining ride quality. Without extensive
research and pioneering of progressive rate
performance suspension springs Eibach
springs will provide the exceptional
handling and precise vehicle responsiveness
and stability with minimal effect to the
ride quality. Eibach suspension components
are designed to allow the suspension to move
in a controlled manner unleashing the
performance potential of the vehicle...
Unleash the power. We want the driver to be
a working component rather than a passive
it necessary to have my vehicle aligned
after installing an Eibach Spring Kit?
Yes. Any time you work on the suspension
system and after the ride height, it is
necessary to check and adjust the alignment
of the vehicle. By lowering the center of
gravity and ride height of a vehicle to
enhance the handling, some negative camber
may occur, which additionally improves
adhesion during performance driving. In
setting up a performance suspension system,
some negative camber is desirable. Eibach
offers alignment kits for selective
applications to assist in performance and
street suited alignment requirements.
competitor' spring kits claim to lower my
vehicle more than the Eibach kits... isn’t
this better? If the vehicle is lower,
won’t it handle more like a racecar?
A spring kit that lowers the vehicle
excessively will be operating with little or
no suspension travel, resulting in an
uncomfortable ride and unsafe handling. The
vehicle may skip over bumps and road
transitions, causing the tires to loose
contact (adhesion/traction) with the road
surface. A race prepared vehicle has a
chassis and suspension designed for use
solely on racetracks. The requirements for
an everyday, street-driven vehicle that
encounters potholes, expansion joints,
weathered tarmac etc. are completely
different. Eibach spring kits lower the
vehicle center of gravity properly while
maintaining adequate suspension travel to
meet the demands of the enthusiasts. Trust
into the experienced Eibach engineers who
have always tried to design the ultimate
sportive suspension. They also have to
dissuade from irresponsible extreme lowered
set-ups, where the vehicle is riding mostly
on the bump stops. This is dangerous and in
most countries illegal!
shocks or struts should I use with an Eibach
Eibach Pro-Kits are designed to work with
original equipment shocks and struts
provided they are in good working condition.
Aftermarket performance shocks and struts
will increase the overall performance of
your suspension and are also recommended for
use with Eibach Pro-Kits. Pro-Damper -
valved by Eibach, is the newly established
line of Eibach performance dampers. The
Eibach Pro-Damper is the ultimate match for
the Pro-Kit as it is the only damper line
which is valved to work in unison with the
Eibach street products street-legal
Eibach’s performance street products
are designed and manufactured to the highest
technical standards, including the DIN EN
ISO 9001 German TÜV, Japanese MOT and the
additional local standards found worldwide.
Eibach performance street products contain
the critical requirements of:
- Maintaining minimum pre-load to
assure positive spring location under
all driving conditions
- Maintain calculated remaining travel
for impressive performance, safety and
- Dynamic durability assurance to
provide years of lasting performance
- Corrosion protection meeting the
requirements of the OEM industry and
Eibach’s critical standards
- Backed with a guarantee and
reputation of the leading performance
Eibach’s Pro-Kit, Pro-Damper,
Anti-Roll-Kit and Pro-Control Bar are legal
in practically all countries around the
world. A few exceptions may apply.
I have proper tire clearance with a
"plus size" wheel & tire
package after installing an Eibach Pro-Kit?
All Eibach suspension kits are designed
and tested around the vehicle’s original
wheel and tire combination as provided by
the manufacturer. The installation of an
Eibach Pro-Kit does not alter the original
range of wheel travel and as a result can
never be the cause of wheel or tire
clearance problems. It is best to work with
a reputable wheel and tire dealer that is
knowledgeable in the proper wheel size
(width and offset) that is correct for your
vehicle in order to prevent clearance
problems caused by improper wheel and tire
is wrong with heating or cutting a coil
spring to lower a vehicle? Index
Heating or cutting a coil spring in order
to lower a vehicle is just plain foolish.
These procedures are very dangerous and at
the very least results in poor handling due
to the changing of the original springs
characteristic and pre-load.
Eibach suspension springs are fitted, will
the car sit at the correct ride height or
will it need time to settle? Index
All Eibach suspension coils are pre-set
to eliminate settling and increase life
expectancy. Some minimal settling may occur
as the new spring mates up to an existing
rubber suspension isolator, this is normal,
but is not the same as a poorly produced
spring which may take a set and effect the
ride height, handling and alignment of the
vehicle has a torsion bar at the rear (or
front). If I lower the front (or rear), how
do I alter the other end of the vehicle?
Vehicles, equipped with coil springs at
one end and torsion bars at the other, have
a height adjustment available from the
factory, which allows altering the ride
height to be compatible with the height of
the Eibach coil springs. The maximum load
capacity of the torsion bar will be reduced.
I just fit front (or rear) springs instead
of the complete front and rear set?
NO!! Eibach suspension springs are
designed as a balance spring system
producing increased performance,
responsiveness and driving enjoyment. Under
no circumstances do we recommend or endorse
the installation of 1/2 of an Eibach spring
it allowed to do the installation of the
springs by myself? Index
NO!! We absolutely warn to install
springs without the proper equipment plus
the experience of a professional work-shop.
A compressed spring usually stores more than
500kg (> 1000 lbs) of dynamic energy!
Unintentional release is absolutely
the Eibach Pro-Kit work with the OEM shock?
All Eibach Pro-Kits are engineered to
perform in harmony with the original damper
of the special vehicle - take for granted a
good working condition. All TÜV approvals
in Germany certify the combination of the
Pro-Kit with an OEM shock.
happens to the warranty of the OEM shock
when combined with Eibach Pro-Kit?
There is no change of the warranty.
Actually, the weight of the car and the
required basic dynamic work remain the same.
Though with special progressive
characteristic of the Pro-Kit, the damper is
challenged more and usually makes it wear
I load the normally allowed load (trunk)
also with an Eibach Pro-Kit? Index
All Eibach Pro-Kits are designed for the
same maximum load like the OE springs.
Actually, a progressive Eibach spring
generates higher resistance under heavier
is the spring rate of the Pro-Kit?
Only simple linear springs have a spring
rate. A sophisticated progressive Eibach
Pro-Kit spring has a load/deflection
characteristic. The special design
parameters are only accessable through
Eibach Desk-Tech Database to Eibach’s
often should springs be replaced? Index
An Eibach Pro-Kit spring usually lasts
and performs for the lifetime of the vehicle
and has not to be replaced. All other
springs should be replaced, whenever you
don’t like the handling of your car.
is Eibach more expensive than other
(no-name) makes? Index
See our first answer of the FAQ’s and
drive and test Eibach’s by yourselves –
then you know the answer.
there a hint how to install the Pro-Kit
Yes! The springs have to be installed
that side up that you can read the printing.
the Eibach Pro-Kits have different colors?
No! All Eibach Pro-Kits worldwide are
coated in diamond-black. Be aware of cheap
copies; also identify the Eibach Logo on the
is the advantage of a progressive set-up –
like the famous Eibach main- and tender
spring combination? Index
Each suspension set-up is a critical
balance between two contradictions:
- as soft as possible and as stiff as
The progressive set-up combines both
- the smooth, softer initial
characteristic for the traction and
- the sportier, stiffer final rate for
reduced body roll and better
responsiveness under curving, braking
