ISC Suspension 04-15 BMW 04-10 BMW 520/523/525/528/530/535 X-Drive/AWD N1 Basic Coilovers - Street

With this kit, you get a complete set of four ISC Suspension N1 Basic coilovers, designed for street use on select BMW 5 Series models with X-Drive or AWD. These coilovers are built to replace your factory suspension components, offering a way to adjust your vehicle's ride height and improve its handling characteristics for daily driving. The N1 Basic line focuses on providing a noticeable improvement in cornering and a more planted feel without the complexity of more advanced adjustable systems.

ISC Suspension builds these N1 Basic coilovers with a focus on durability and consistent performance for everyday driving. They feature a monotube design, which helps with heat dissipation and provides more responsive damping compared to twin-tube designs. The spring rates are chosen to offer a firmer ride than stock, reducing body roll during cornering and providing a more connected feel to the road. While these are the 'Basic' model, they still incorporate features like adjustable lower mounts for ride height tuning, allowing you to dial in the stance you want. The upper mounts are typically designed as direct replacements for the factory units, simplifying the installation process. These are intended for drivers who want a noticeable upgrade in handling for their AWD BMW 5 Series without needing a full track-oriented setup.

When installing these coilovers, you'll be replacing your entire strut and spring assembly at each corner. It's a good idea to have a professional alignment done after installation to ensure everything is set up correctly and to maximize tire life. While these are designed for street use, the improved damping and spring rates will make a difference on spirited drives as well.
