Description
Nissan Z33 350Z Fairlady Z (03-09) BC Racing ZX coilover kit 9/8 kg/mm
The BC Racing ZX coilover kit 350Z (part number D-17-ZX) 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.
With this kit your Z33 gets 3-way adjustable dampers. This is the standard version: at the rear the original layout with a separate spring and a separate damper is retained, as the Z33 has from the factory. You will find a complete strut at the rear in the True Rear version.
The ZX is built for competition use. It combines the digressive piston of the DS with the external reservoirs of the ER and adds 3-way adjustment. You adjust low-speed compression, high-speed compression and rebound each separately.
The spring rate is 9/8 kg/mm, a balanced choice for a Z33 that has to be capable of a lot both on the circuit and when drifting.
Key benefits
- Standard rear layout: separate spring and damper at the rear, as from the factory.
- 3-way damping adjustment: 20 clicks LS compression, 12 clicks HS compression, 30 clicks rebound.
- Dual piston with external reservoir: more oil volume for stable damping.
- Combination of DS and ER: digressive tuning plus reservoir technology.
- Ultra-high VI racing oil: stays consistent when it gets hot.
- Camber plates: with replaceable upper mounting, rubber top mounts optional.

Fitting and delivery
The kit replaces the dampers and springs all round. Mount the reservoirs carefully and after fitting have the wheel alignment and the corner weights set accurately, because the ride height directly affects camber and toe. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. Out of stock? You can still order and we will keep you informed.
A Z33 you can tune click by click for every corner, every kerb and every drift zone.
Why choose this ZX coilover kit 350Z?
At competition level, what makes the difference is how the car responds to sharp impacts and how it transfers weight. With three separate settings you tackle those two independently of each other. You do not have to compromise between grip over kerbs and stability in the corner.
