ISC Suspension 2015 Subaru WRX/STI N1 Basic Coilovers

If you're looking to dial in the stance and handling of your 2015 Subaru WRX or WRX STI, these N1 Basic Coilovers from ISC Suspension are a solid option. They replace your factory struts and springs, giving you the ability to adjust both your ride height and the damping force. This means you can lower your car for a more aggressive look or tune the suspension for better performance on the street or track.

ISC Suspension builds these coilovers with a focus on providing a noticeable improvement in handling without breaking the bank. The N1 Basic series uses a monotube shock design, which generally offers better damping control and heat dissipation compared to twin-tube designs, especially during spirited driving. The spring rates are chosen to offer a firmer ride than stock, which helps reduce body roll when cornering. You also get adjustable damping, allowing you to fine-tune how the suspension reacts to bumps and undulations in the road. The spring perch collars are made from aluminum, and the lower mounts are steel, offering a good balance of strength and corrosion resistance for daily use.

When installing these coilovers, you'll be replacing your entire strut and spring assembly. It's a good idea to have an alignment done after installation to ensure your wheels are pointing straight and your tires wear evenly. These coilovers are designed to fit your 2015 WRX or WRX STI directly, meaning no modifications are needed for installation. You'll be able to set your desired ride height using the adjustable spring perches.
