Adjustable Damping on All 2015 STI Coilovers:
ISC Coilovers all come with 32 way adjustable damping that is rebound and compression in unison via 32 step adjustment.

Single Cylinder Mono-tube Design:
Large
cylinder and piston design work hand in hand to increasing driving 
stability and dexterity. ISC utilizes a mono-tube design damper, not 
twin tube like other manufacturers. Mono-tube dampers provide consistent
valving and much less potential for cavitation. They are also high 
pressure to reduce body roll, and are 100% efficient through all 
temperatures. Our larger pistons also allows more oil which provides 
better damping control and the ability to absorb higher forces. All ISC 
Dampers also utilize a double o-ring to prevent leaks.

Multiple Valving Options:
ISC Suspension offers three valving options to choose from, street comfort, street sport, and track race. 

Street
Comfort is designed to feel close to OEM and is the most comfortable 
valving that we offer. If you are looking for a mild drop and 
comfortable ride this is for you!

Street Sport
is designed to be above OEM, and is more aggressive and ideal for 
street, drift, and occasional autocross. If you're looking to bring your
car to its limits on the street, this one is for you!

Track Race
is our most aggressively valved and is suggested for road course, 
slammed show cars, and some form of drifting. If you are installing 
these coilovers on a dedicated weekend track car, this option is for 
you!

ISC also offers custom valving, please contact for an accurate ETA.

Piston Rod Design:
ISC
utilizes high rigidity steel piston rods that meet all race and sport 
standards. ISC shafts are valved according to the spring rate chosen by 
the customer. A shock dyno is used to ensure quality and consistent 
results. All ISC dampers are 100% fully rebuildable.

Upper Mounts:
For optimal performance pillowball upper mounts are a great feature. ISC includes these upper mounts of all N1 Systems.

Front Camber Plates:
When your vehicle's suspension geometry allows all ISC N1's come with adjustable camber plates standard.

Thrust Bearings:
While
many coilover companies charge for thrust bearings ISC does not. These 
come standard on all N1 coilovers and help to eliminate spring bind; a 
common side effect of utilizing aftermarket coilovers.

Sport Spring:
ISC
Suspension offers a variety of different spring's rates. Our springs 
are made from high quality SAE9254 Steel. They are dyno tested over 
500,000 times on a compression inspection with less than 5% deformation.
We are fully capable of offering custom spring rates as well! Every 
driver is different and we understand some may need custom spring rates.

Ride Height Adjustable:
Full
length height adjustability. Most applications can achieve 3 inches or 
more. High quality T6061 aluminum allow used for all adjustment locks to
provide a lightweight design that holds spring and vehicle force down.

Bound Adjustable with Separate Spring Locks:
Preload is separate from ride height; the lower you go the quality of the ride stays the same!

Aluminum Brackets:
Made
from T6061 aluminum allow by organic shaping to lighten weight and 
increase handling performance. ISC Gold or Black anodized surfaces help 
to prevent corrosion and surface rust. Most applications also feature 
mounting points for OEM brake line installation.
