We talk about ISC Suspension a lot here at AJW Performance it’s primarily because we are such huge fans of their products! ISC Suspension has been creating quality and affordable coilovers for quite a few years now. They know what people want and they find ways to give it to them without breaking the bank or cutting corners. Their coilovers for the 2008 – 2014 WRX and STi are no exception. These two vehicles (WRX, and STi) have been huge sellers for Subaru in the past few years. The GE, GV, GH, and GR have been some of the best sellers for AJW Performance over the past few years. Primarily we see the most demand coming from the GR and GV crowd. Introducing the Widebody to the WRX was a great move on Subaru, and allowed Subaru owners with WRX’s to have a great looking car with a little bit more wheel base.
ISC Suspension’s coilovers for the GR and GV WRX really have the ability to slam the car. They offer up to three inches of adjustability and at max height the rear coilovers are just above tucking tire. If you’re looking for a kit to get low these are them! They’re also good for track use though and can also obtain stock ride height with a different coilover shaft. If that’s something you want just make sure to tell us!
The coilovers for the 2008 – 2014 WRX and STi feature 32 way adjustable damping as well as independent pre-load and adjustable ride height.
The official description for these coilovers can be found below:

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.
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 (vehicle specific, please check our application guide) 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. 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.
Swift springs also available as an upgrade visit here for more information: Swift Springs
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!
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.
