ISC Suspension 97-98 Mitsubishi EVO 4 GSR N1 Coilovers

If you're looking to dial in the suspension on your 1997-1998 Mitsubishi Lancer Evolution 4 GSR for track days or spirited driving, the ISC Suspension N1 coilovers are a solid option. These are built to give you a wide range of adjustability for ride height and damping, letting you fine-tune how your car handles corners and rougher roads. They replace your factory struts and springs with a complete, integrated coilover assembly, making for a cleaner installation and a more unified suspension system.

ISC Suspension uses monotube dampers in the N1 series, which generally offer better heat dissipation and more consistent damping performance compared to twin-tube designs, especially under hard use. The spring rates are chosen to offer a noticeable improvement in body control without making the ride overly harsh for street use, though you can expect it to be firmer than stock. You can adjust the ride height independently of the spring preload, allowing you to set your desired stance and corner balance without compromising suspension travel. The damping adjustment is typically a 30-click range, giving you plenty of options to dial in the feel for different track conditions or street driving preferences.

When installing these coilovers, you'll be replacing your entire strut and spring assembly. It's a good idea to have a torque wrench handy to ensure all mounting hardware is tightened to spec. Because these are adjustable, you might want to consider getting a professional alignment done after installation to ensure your tire wear is even and your steering feels right. These coilovers are designed to work with your factory suspension mounting points, aiming for a direct fit.
