The Cusco Sport R 24-Way Adjustable Coilover Kit is a high-performance suspension component designed for circuit driving and precise handling. Featuring monotube shock absorbers with a single-cylinder structure, these coilovers offer 24 levels of damping force adjustment, allowing for fine-tuned control over ride stiffness and responsiveness. The kit incorporates Cusco's innovative "Blue spring" technology, enhancing durability and performance. Full-length vehicle height adjustment and pillow ball upper mounts provide customizable setup options, ensuring optimal alignment and handling characteristics. Constructed with high-quality materials, these coilovers are engineered to deliver superior stability, reduced body roll, and improved cornering capabilities, making them ideal for enthusiasts seeking a competitive edge on the track.

Designed specifically for 2003-2004 Subaru Impreza WRX STi models, these coilovers are compatible with vehicles equipped with S tires and feature front strut type suspension. They serve as direct replacements for stock components, offering an upgrade in both performance and adjustability. The kit is suitable for street and circuit use, providing precise damping control and height customization to suit various driving conditions. Installation involves replacing existing struts with these coilovers, and the kit includes the necessary components for a straightforward upgrade. Whether for daily driving or track days, these Cusco coilovers enhance handling dynamics and driver confidence.

Overview

Full specifications for circuit driving that enable precise setting

  • Monotube shock absorber
  • 24 steps of damping force adjustment
  • Newly developed CUSCO SPORT "Blue spring" adopted
  • Full length adjustable vehicle height adjustment
  • With pillow ball upper mount * Excluding some models
  • Ram type (inverted type) shock absorber *Front strut type only
  • Compatible with S tires

Monotube shock absorber

  • A structure in which the shock absorber body is a single cylinder. By increasing the diameter of the piston and improving the valve, etc., it generates a delicate damping force from minute inputs from the road surface, and follows even faster piston speeds. In addition, since the cylinder (tube) is in direct contact with the outside air, it has excellent heat dissipation and exhibits stable damping force characteristics.

24 steps of damping force adjustment

  • 24-step damping force adjustment using an ultra-precision special needle valve that enables precise settings

Full length adjustable vehicle height adjustment

  • "Overall length adjustment type" that does not change the suspension stroke even if the vehicle height is lowered. Both fine vehicle height adjustment and high ride comfort are achieved.

Newly developed CUSCO SPORT "Blue spring" adopted

  • The double shot peening process has increased the strength and greatly improved the resistance to settling, and by making the tolerance extremely small, we have made it possible to set more precisely than ever before.

Upper mount

  • The strut type front adopts a camber adjustable pillow upper mount, and other than that, a camber fixed reinforced rubber upper mount is set. A center lock pillow upper mount (sold separately) can be installed on vehicles with no upper mount. Newly developed CC pillow upper mount (camber and caster independent adjustment type) is available as an option for some front strut type models.

Ram type (inverted type) shock absorber

  • Only the strut type uses a ram type shock absorber in which the piston rod extends downward from the main body. It is effective in reducing unsprung weight, is strong against lateral G, and has excellent heat dissipation.
