Fortune Auto 1989 - 1994 Silvia/180SX/240sx (S13) Optional 7K

Fortune Auto Gen 8 - 500 Series dampers are hand-built for optimal quality. Developed on the racetrack, these 510 Series coilovers offer comfort, reliability, and longevity. Featuring Flow Digressive piston technology for stiff low-speed compression/rebound, improving control during roll, dive, and squat. At high stroke speeds (e.g., bumps), the suspension becomes supple for maximum control. The advanced Concave Flow Digressive Piston provides a dynamic adjustment range, eliminating the need for revalves (tolerates an 8kg spring rate difference vs. 2kg for conventional shocks). This allows for quick track tuning and a 'Jekyll and Hyde' personality: lower spring rates can be stiffened via damping, while higher rates feel smoother, ensuring both comfortable street ride and track performance with a single adjustment knob. Upgradeable and rebuildable.
