ISC Suspension 95-98 Nissan 240SX (Silvia) N1 Coilovers

ISC Suspension is known for making well-built suspension components, and their N1 Coilovers for the 1995-1998 Nissan 240SX (S14 chassis) are a prime example. If you're looking to dial in your suspension for better handling, whether for spirited street driving or track use, these coilovers are designed to give you a lot of control over your car's stance and feel. They replace your factory struts and springs with an integrated, adjustable unit, allowing you to fine-tune ride height and damping characteristics.

These N1 coilovers feature a monotube design, which generally offers better damping control and heat dissipation compared to twin-tube designs, especially under demanding conditions. You get a significant range of adjustment for ride height, letting you lower the car to your desired look and center of gravity. The damping is also adjustable, typically with a range of settings that allow you to stiffen or soften the suspension to match your driving style and road conditions. The spring rates are chosen to offer a noticeable improvement in body control without being overly harsh for daily use, though specific rates are not listed here. The upper mounts are often designed to be pillowball or camber adjustable, giving you further tuning options for wheel alignment.

When installing these coilovers, you'll be replacing your entire front and rear strut assemblies. It's a good idea to have a proper spring compressor if you plan on reusing your original top mounts, though these units come as complete assemblies. After installation, it's highly recommended to get a professional wheel alignment to ensure your tires are tracking straight and true, maximizing performance and tire life. These coilovers are a solid option for 240SX owners looking to significantly upgrade their suspension's capabilities.
