ISC Suspension 11-15 Kia Optima N1 Basic Coilovers - Race/Track

The 55mm monotube damper body in these ISC Suspension N1 Basic coilovers is a key feature for track-focused performance on your 2011-2015 Kia Optima. This design helps maintain consistent damping even under the high temperatures generated during spirited driving and track sessions. These coilovers are specifically tuned for race and track applications, offering a more aggressive setup than a street-oriented coilover. They allow for significant ride height and damping adjustments, giving you the control to dial in your suspension for optimal handling on the circuit.

Built with durability in mind for demanding use, the N1 Basic coilovers feature robust construction. The spring perch collars are made from strong aluminum, and the lower mounts are forged steel for added resilience. The damping is adjustable across 32 levels, allowing you to fine-tune the compression and rebound characteristics to match track conditions and your driving style. This level of adjustability is crucial for maximizing grip and responsiveness when you're pushing your Optima to its limits.

When installing these coilovers, you'll find they are designed to fit your Kia Optima directly, replacing the factory strut and spring assembly. While they are built for track performance, they offer a noticeable improvement in handling and body control for spirited street driving as well, though they will provide a firmer ride. It's recommended to have these professionally installed or to consult the manufacturer's installation guide for proper setup and alignment procedures to get the most out of their performance capabilities.
