BC Racing DS Series Coilovers for the 2002-2006 Infiniti Q45 (F50) use a new proprietary digressive piston design that offers increased damping force at low piston velocities while maintaining a linear damper feel at higher piston velocities.
One of the greatest advantages of increased low-speed damping force relates to what the driver feels, e.g. roll, pitch, dive, and quick weight transitions on technical road courses.
For the ultimate in driver feel, choose the BC Racing DS Series Coilover System. BC Racing DS Coilovers are the most popular track coilover from BC Racing.
