Looking to rake your Z4 / M Coupe suspension
to the next level at the track? You've tried the rest and now KW is
offering you the BEST!
is getting more and more famous world-wide. Therefore, KW has decided to
develop a new product line – KW Clubsport. This new product line is
distinguished by motorsport applications for race track and road use
with ideal performance.
Nürburgring Nordschleife is the most popular race track for using our KW
Clubsport suspension kits. High performance sports cars, modified
saloons as well as classical sport compact cars are tuned in weight,
engine and wheels for their use on several race tracks. These
improvements are made for a better handling on track sport events, race
taxi drives, visitor drives and equability tests particularly on the
Nürburgring Nordschleife. Due to these modifications of the car some
parameters are changing. Therefore, the road setups are no longer ideal
for the performance of the car. For this use we offer special clubsport
kits which have been adapted to the changed requirements by changing
spring and shock setup as well as the installation of racing top mounts
Warranty is not
offered with KW Clubsport Coilovers due to the fact that these were
exclusively designed to be used on the track; excessive wear and tear
are expected with such use as track driving.

What are coilovers?
A coilover suspension basically gives you a matched lowering spring and
shock absorber combination with the added benefit of adjustable ride
height and spring rates through a moveable spring perch or perches.
Coilovers are to your car's advantage by reducing unsprung mass,
increasing suspension travel, and allowing the car to be corner
