Frequently Asked Questions
Engineered for the Porsche 911 (996) Carrera 2, the Riaction GP-1 Digressive Coilover Kit features digressive valving technology designed to match the precision and balance of the 996 chassis. This damping profile delivers firm low-speed control for sharper turn-in and improved chassis stability, while maintaining compliance over uneven surfaces—resulting in a ride that remains composed without sacrificing comfort.
Built for drivers who value control and feedback, this system enhances cornering confidence, improves weight transfer, and delivers a more connected driving experience for both street and spirited driving.
Each kit is constructed using high-quality materials and precision engineering to ensure durability, reliability, and consistent performance.
