The ISC N1 Coilover system is the optimum suspension tool for improved handling for your street, track, or drift car. This product is perfect for someone looking for performance, adjustability, and other high quality features in a package that will not break the bank. ISC coilovers are also 100% rebuildable!

ISC’s self-manufactured N1 allows them to have top grade quality control and innovative R&D capabilities due to their in house/self-made company dynamic. ISC Suspension utilizes some of the best modern engineering techniques and suspension design. ISC has been present in the world for over 13 years and has accomplished drift, road course, street, and other various podiums alike. Over a decade of experience, knowledge, engineering, and feedback have shaped the ISC N1 system into what it is today. All ISC Coilover systems are proudly serviced and distributed in Gilford, NH.

ISC Coilovers all come with 32 way adjustable damping that is rebound and compression in unison via 32 step adjustment.

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. The larger pistons also allow 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.

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 they 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 the 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 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 with all N1 Systems.

When your vehicle’s suspension geometry allows it, all ISC N1’s come with adjustable camber plates standard.

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.

ISC Suspension offers a variety of different spring’s rates. ISC 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. ISC is fully capable of offering custom spring rates as well! Every driver is different and ISC understands some may need custom spring rates.

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

Preload is separate from ride height; the lower you go the quality of the ride stays the same!

Made from T6061 aluminum alloy using 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.

Our BR model is perfect for street driving and occasional road course duty. With easily accessible adjustment knobs for fine tuning your compression/rebound and separately adjustable ride height, having a performance coilover system couldn’t be any easier. You choose how low or high you want your vehicle, no preset ride height here, and our patented concave lower locking ring keeps it locked in. All of our systems come with pillowball mounts to provide the most feedback possible from your suspension and to sharpen your steering response. BC’s available front and rear camber plates also allow you to get the perfect alignment setup without compromise. All this while providing a strong, attractive looking coilover system.
