ISC Suspension 11+ Scion tC N1 Track/Race Coilovers

The 55mm monotube damper design in these ISC Suspension N1 coilovers is a key feature for track and race applications. This design allows for a larger piston area, which helps with consistent damping force even under heavy use. These are built for the 2011 and newer Scion tC, giving you a significant upgrade over the stock suspension for spirited driving or track days.

ISC Suspension uses a digressive valving stack in these N1 coilovers. This means the damping force increases more rapidly at lower shaft speeds, which helps control body roll and keeps the tires planted during aggressive cornering. The spring rates are set at 10kg/mm for the front and 8kg/mm for the rear, providing a firm yet controlled ride that’s well-suited for performance driving. The spring perches are fully adjustable, allowing you to dial in your ride height precisely to your preference or track requirements.

These coilovers are constructed with durable materials to withstand the rigors of track use. The top mounts are pillow ball units, which help transmit steering feel directly to the driver and allow for camber adjustment on the front struts. While these are designed for performance, they are intended to fit directly onto the 2011+ Scion tC without major modifications, making installation more straightforward. If you're looking to significantly improve your tC's handling and responsiveness on the track or during aggressive street driving, these N1 coilovers are a solid option.
