ISC Suspension 99-02 Nissan Silvia N1 Coilovers

These ISC Suspension N1 coilovers are made for the 1999-2002 Nissan Silvia. They offer a way to adjust both your vehicle's ride height and the stiffness of its suspension. This allows you to fine-tune how your car handles, whether you're looking for a lower stance or improved cornering performance on the street or track.

The N1 series coilovers feature a monotube design, which generally offers better damping control and heat dissipation compared to twin-tube designs. They come with 24 levels of damping adjustment, letting you dial in the suspension feel from comfortable cruising to firm, track-ready stiffness. The spring rates are set at 10kg/mm for the front and 8kg/mm for the rear, providing a noticeable improvement in body control without being overly harsh for daily driving. The upper mounts are typically pillow ball or rubber, depending on the specific application, to help isolate noise and vibration. Installation involves replacing your factory strut and spring assembly with these complete units.

When installing these coilovers, it's a good idea to have a torque wrench and the appropriate sockets to ensure everything is tightened to spec. Because these are a complete assembly, they are designed to fit directly onto your Silvia's existing mounting points, making the swap straightforward. You'll want to set your desired ride height and damping settings before final alignment. It's also recommended to check the manufacturer's instructions for any specific break-in procedures or torque recommendations.
