Nissan Z33 350Z Fairlady Z (03-09) BC Racing DS coilover kit 9/8 kg/mm

The BC Racing DS coilover kit 350Z (part number D-17-DS-DS) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Nissan 350Z and Fairlady Z (Z33), model years 2003 to 2009. The spring rate is 9 kg/mm front and 8 kg/mm rear.

The kit gives the Z33 track-focused, digressive damping. It is the standard version: the original layout with separate spring and separate damper is retained at the rear. If you would rather have a complete strut with the spring around the damper at the rear, choose the True Rear version.

The digressive piston damps firmly at low speeds, so the Z33 rolls and dives less. With fast impacts over bumps and kerbs it allows more movement, so the tyres keep their grip. That makes the DS suitable for track days and drifting.

The spring rate is 9/8 kg/mm and you adjust the damping in 30 clicks. You set the ride height independently of the spring preload.

Key benefits

• Factory rear layout retained: separate spring and damper as original.
• Digressive damping: extra control between 0 and 50 mm/s.
• 30-click damping adjustment: compression and rebound together.
• Ride height independent of preload: lower without sacrificing stroke.
• Satin chrome damper bodies: the typical DS finish.
• Concave lower lock ring: holds the setting.
• Spring rate 9/8 kg/mm: a well-balanced setup for the Z33.

Suitable for

Nissan 350Z and Fairlady Z Z33, model years 2003 to 2009

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs; the layout at the rear stays the same. Have the wheel alignment checked after setting the height. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. No stock? You can still order, and we will keep you informed.

Less roll, less dive and still grip over the kerbs: the DS lets a 350Z do what you ask of it through the steering wheel.

Why choose this DS coilover kit 350Z?

You get track-focused damping without converting the rear of your Z33. A good middle ground between the all-round BR and the reservoir series, with a clearly noticeable difference on track.

Frequently asked questions

What is the difference between the standard and the True Rear version of the BC Racing DS for the Nissan 350Z?

This standard version (D-17) keeps a separate spring and separate damper at the rear and has 9/8 kg/mm. The DS True Rear (D-107-DS-DS) creates a complete strut with the spring around the damper at the rear and has 9/5 kg/mm.

What is the difference between the BC Racing DS and ER for the Nissan 350Z?

The DS coilover kit 350Z has no external reservoir and adjusts compression and rebound together. The ER has reservoirs and adjusts both independently of each other, for serious track work.
