GP-1 DIGRESSIVE LEXUS GS300 (98-05)
SKU: LX-003-D-SS
Engineered for the Lexus GS300, the Riaction GP-1 Digressive Coilover Kit features digressive valving technology designed to enhance both performance and ride quality. This damping profile delivers firm low-speed control for improved handling and reduced body movement, while maintaining compliance over uneven road surfaces—resulting in a ride that feels stable yet comfortable.
Well-suited for street-driven builds, this system provides a lower stance, improved cornering confidence, and more direct road feedback while maintaining the refinement expected from a luxury chassis.
Each kit is constructed using high-quality materials and precision engineering to ensure durability, reliability, and consistent performance.
