ISC Suspension Coilovers

ISC Suspension made its name with the N1 coilover, a fully adjustable kit backed by a standout warranty at a genuinely accessible price. At Springrates we carry the ISC N1 range across a wide list of makes and models.

ISC N1 Coilovers: Adjustability and Value

The ISC N1 is a monotube, fully adjustable coilover offering 32 levels of damping and full-length height adjustment. What sets ISC apart is the support behind it — the kits carry a long warranty and are rebuildable, so you're not buying a disposable coilover. It's a lot of engineering and peace of mind for the price.

The ISC N1 Lineup

ISC offers the N1 in several tunes: the N1 Basic for a straightforward street drop, the N1 Street Sport for a balance of comfort and performance, and the N1 Track/Race for stiffer, track-focused setups. That range lets you match the spring rates and character to how you actually use the car, all within the same proven platform.

Are ISC Coilovers Any Good?

ISC earns strong reviews for value, adjustability, and especially customer support and warranty. For a street or street-and-track build that wants real height and damping adjustment without a premium price, the N1 is an easy recommendation. ISC also offers coilover covers and other accessories to protect and personalize your setup.
