ISC Suspension 99-03 Acura TL N1 Basic Coilovers

This ISC Suspension N1 Basic coilover kit includes a full set of four coilovers, designed specifically for the 1999-2003 Acura TL. These units combine the spring and shock absorber into a single, adjustable assembly, allowing you to dial in your ride height and damping characteristics. They are a popular choice for TL owners looking to lower their vehicle and improve handling beyond what stock suspension can offer.

The N1 Basic series from ISC Suspension is built with a focus on providing a solid performance upgrade without unnecessary complexity. Each coilover features a monotube shock design, which generally offers better damping control and heat dissipation compared to twin-tube designs, especially under spirited driving conditions. The spring rates are chosen to offer a noticeable improvement in body control and reduced roll during cornering, while still maintaining a reasonable level of comfort for daily driving. You'll find the damping adjustable on each unit, allowing you to fine-tune the stiffness to match your driving style and road conditions. Installation involves replacing your existing struts and springs with these complete assemblies.

When installing these coilovers, it's important to ensure proper alignment is performed afterward to get the most out of the new suspension geometry and to prevent uneven tire wear. While these are a direct replacement for your factory struts and springs, it's always a good idea to inspect your other suspension components, like control arms and bushings, to ensure they are in good condition before making the upgrade.
