(SS) Sport Street Coilovers
The POWERTRIX (SS) Sport Street Coilover System is the most
complete and fully featured street Coilover kit on the
market. Unlike all other entry level units on the market
which required the use of the stock shock upper mounts and
bushings, the (SS) Sport Street Coilover System is now complete
with upper mounting hardware and is now a true complete bolt
in system. With our new SS Coilovers, the tedious process of
disassembling the stock shock upper mounts and bushings just
to find out that you may need to buy new hardware is now
non-existent with the installation. These new SS upper
mounts are fitted with a synthetic butyl bushing in place of
a pillow ball. This bushing combines just enough density to
transfer suspension energy properly yet not overly stiff to
help with dampening the stiff ride quality that is inherent
with conventional race Coilovers and solid pillow ball
mounts.
Also unlike most entry level coilovers, that adjust ride
height through spring preload, the POWERTRIX SS adds an
extra dimension of adjustment with independent ride height
adjustability through the threaded bottom mounting brackets.
With this set up it properly separates spring preload and
ride height, a feature only found on upper line coilovers.
Geared for the aggressive everyday street driver with the
occasional autocross and road course event, 15 way
adjustable strut dampening is valved a notch softer that our
full (RT) Road/Track and (UL) Ultra-Lite Road/Track Coilovers. This kit is a
formidable track performer as it is the best of both worlds:
Daily Driver/Weekend Warrior
Features List:
» Rebuild-able/Replaceable Premium mono-tube forge steel strut
Body
» SS upper mounts (for a complete bolt-in solution) no need
for any OEM Hardware
» 15 way strut damper adjustments
» Independent Ride height and Spring Preload adjustability
» 8kg/mm front and 6kg/mm rear Helper Springs included for
extreme ride height lowering (Front Only)
All coilover kits are rebuild-able so it will
be the last strut and spring combination you will ever need.
Fine tuning of the suspension is also possible for any and
every type of driving style, or motorsports events as custom
spring rates are available from 3kg/mm (168 lbs/in) –
17kg/mm (952 lbs/in)
Note: + or – 2k on spring rate changes will require re-valving.

(RT) ROAD/TRACK Coilovers
The (RT) Road/Track Coilovers feature a robust Race grade 45mm mono
tube strut piston that is valved for the serious competitor
and features aluminum pillow ball upper mounts to transfer
more suspension energy through the strut piston shaft
increasing the efficiency of the overall suspension duty.
Full forged steel threaded shock bodies for independent ride
height and spring preload adjustability and 13k/11k linear
springs make the RT Coilover System an "All Business" tool
for Auto crossing and Road Racing. Designed for the true
performance enthusiast looking for the extra edge during
track time, it is also just civil enough to run on the
street on a daily basis.

(UL) Ultra-lite ROAD/TRACK
Coilovers
The (UL) Ultra-Lite Road/Track Coilovers are the ultimate in all-around
performance and handling. It also features the aluminum
pillow ball upper mounts and independent ride height and
spring preload adjustability. For the serious Motorsports
competitor, the UL version shares all the same
features of the Race version but incorporates aluminum strut
housings for an approximate 10% decrease in weight making
them the competitor’s choice for those watching un-sprung
weight. We have used these coilovers for dual duty, Drag and
Autocross setups with great Success. With all the adjustment
and spring options, it is possible to set up the vehicle to
meet all situations and scenarios. Thought the strut housing
is aluminum to save weight, the POWERTRIX (UL) Ultra-Lite
coilovers use heat tempers forged steel for bottom mounting
cups (where other companies use aluminum) for maximum
strength where is it needed the most at the point of where
the coilover assembly bolts to the hub of the car.
The (UL) Ultra Lite Road/Track Coilovers aluminum shock bodies make an
entire assembly approximately 2-3 lbs. lighter than the
standard (RT) Road/Track version coilover assembly. Though this does
not sound like a lot, it can make a big difference
performance-wise when the dynamics of sprung vs. un-sprung
weight is considered.
Sprung weight is defined as a parts weight while in motion
or constant oscillation. Un-sprung weight is the actual
weight of the part as it is at rest or not in motion. Sprung
weight is calculated to be approximately 3-4 time its
un-sprung weight.
Therefore a coilover assemble that is 2-3 time lighter than
another can be as much as 6-12 lbs. lighter while in motion,
so calculating that savings on each corner of the car can be
as much as 24-48 lbs. of weigh savings.
