Nissan Z33 350Z True Rear Fairlady Z (03-09) BC Racing DS coilover kit 9/5 kg/mm

The BC Racing DS coilover kit 350Z True Rear (part number D-107-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, in True Rear version. The spring rate is 9 kg/mm front and 5 kg/mm rear.

The kit is intended for Z33 drivers who mainly use their car on track. True Rear means that the rear becomes a complete strut, with the spring around the damper. The original Z33 has a separate spring and a separate damper at the rear; you will find that construction in the standard version.

The DS series has a digressive piston. At slow body movements, such as roll and dive, it damps firmly. At fast wheel movements over bumps and kerbs, on the other hand, it gives more, so that the tyres keep contact.

The spring rate is 9/5 kg/mm and you set the damping in 30 clicks. You set the ride height independently of the spring preload.

Key benefits

• Complete strut at the rear: True Rear with the spring around the damper.
• Digressive damping: firm at 0 to 50 mm/s, supple on fast impacts.
• 30 clicks: compression and rebound adjustable together per damper.
• Height independent of preload: low without giving up damper stroke.
• Satin chrome damper body: the recognisable DS version.
• Concave lower lock ring: stays reliably in place.
• Spring rate 9/5 kg/mm: matched to the True Rear construction.
• Rebuildable: can be rebuilt later instead of replaced.

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

• Track days and drifting

Fitting and delivery

The kit replaces the original springs and dampers; at the rear, the separate construction is replaced by a coilover. We recommend having it fitted by an experienced mechanic. Then have the wheel alignment set. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If there is no stock, you can still order and we will keep you informed.

The same coilover at the rear as at the front and a digressive piston all round: that is how a Z33 keeps its composure in every fast corner.

Why choose this DS coilover kit 350Z True Rear?

You get track-focused damping and the freedom to set up the rear precisely, at a price well below the reservoir series. A logical step for anyone who wants more than the BR but does not yet need 2-way adjustment.
