RS-R 89-94 Nissan 240SX (S13) Sports-i Coilovers

If you're looking to dial in the suspension on your 1989-1994 Nissan 240SX (S13) for track days or spirited driving, the RS-R Sports-i coilovers are a solid option. These units are built to give you precise control over your car's handling characteristics, allowing you to fine-tune both ride height and damping force to match your driving style and track conditions. They replace your factory struts and springs with an integrated, adjustable assembly designed for improved performance.

The Sports-i series from RS-R features a monotube shock design, which generally offers better heat dissipation and more consistent damping compared to twin-tube designs, especially under heavy use. They come with 36 levels of damping adjustment, giving you a wide range to work with, from a comfortable street setting to a firm track-oriented setup. The spring rates are carefully selected to work with the damping adjustments, aiming for a balance between grip and compliance. You'll also find adjustable spring perches, allowing you to set your desired ride height, and camber adjustable pillow ball upper mounts on the front, which are crucial for aligning your wheels correctly after lowering the car.

When installing these coilovers, you'll be replacing your entire front and rear strut assemblies. The pillow ball mounts mean you'll likely hear more road noise and vibrations than with rubber mounts, which is typical for performance suspension components. It's recommended to have a professional alignment done after installation to ensure optimal handling and tire wear. These coilovers are designed to be a direct replacement for your stock suspension components, simplifying the installation process.
