ISC Suspension 05-14 Ford Mustang S197 N1 Coilovers - Street

The threaded portion of the shaft on these ISC N1 Basic coilovers is powder coated and then salt spray coated, giving it solid durability against the elements. These coilovers are built for the 2005-2014 Ford Mustang S197 chassis, offering a significant upgrade over stock suspension for street driving. They feature a monotube damper design with high-pressure nitrogen, which helps advance driving stability and dexterity. The larger cylinder and piston design further contributes to a more controlled feel on the road.

ISC Suspension has been refining their coilover designs for over a decade, and this N1 Basic kit benefits from that experience. Unlike more track-focused setups, these use rubber isolated top mounts in the front instead of adjustable camber plates. This choice simplifies the design, making them ideal for daily drivers who want improved handling without the need for aggressive alignment adjustments. The ride height is fully adjustable, allowing you to lower the car up to 3 inches, and the spring preload is set independently from ride height, so you can achieve a lower stance without sacrificing ride quality. The 32-way adjustable damping lets you fine-tune compression and rebound together to match your driving preferences.

Included with this kit are ISC's Triple S upgraded springs, made from high-tensile SAE 9254 steel. These springs are about 20% lighter than standard steel springs and are dyno-tested for consistency. You'll also find 3mm neoprene coilover covers included, which help protect the dampers from dirt and debris, ensuring they continue to adjust smoothly for years. ISC Suspension also backs these coilovers with a lifetime warranty against defects in workmanship and materials for the original purchaser.
