Nissan Z34 370Z Fairlady Z (08-20) BC Racing DS coilover kit 9/10 kg/mm

The BC Racing DS coilover kit 370Z (part number D-30-DS-DS) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Nissan 370Z and Fairlady Z (Z34), Coupe and Roadster, model years 2008 to 2020. The spring rate is 9 kg/mm front and 10 kg/mm rear.

Anyone who uses their 370Z on the circuit more often soon looks at BC Racing’s DS series. The difference from the BR is in the piston: the DS damps digressively and is therefore firmer between 0 and 50 mm/s. That keeps the body of the Z34 flatter when turning in and braking. You set the damping in 30 clicks, the ride height independently of the spring preload, and the damper body is satin chrome plated.

This DS is the standard version for the Z34: at the rear, the spring and the damper remain separate from each other, just as on the original car. If you want a rear layout with the spring around the damper, choose BC Racing’s True Rear kits, with part numbers starting with D-121.

The BC Racing DS for the Nissan 370Z (Z34) damps digressively, with firmer damping between 0 and 50 mm/s, and has a spring rate of 9 kg/mm front and 10 kg/mm rear.

Why choose this DS coilover kit 370Z?

The 370Z is heavy and has a lot of torque, and on the circuit you want the car to stay calm as the weight shifts. The digressive DS helps with that by damping more firmly at slow body movements. With 30 clicks you tune the kit for the circuit or for the drive there, and the dampers are rebuildable.
