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:
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.
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!
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!

slammed show cars, and some form of drifting. If you are installing

ISC also offers custom valving, please contact for an accurate ETA.
Piston Rod Design:
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.
For optimal performance pillowball upper mounts are a great feature. ISC includes these upper mounts of all N1 Systems.
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.
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. Triple S Springs also available as an upgrade visit here for more information: Triple S Springs
