Description
Nissan S14 Silvia 200SX (95-99) BC Racing ZX coilover kit 6/4 kg/mm
The BC Racing ZX coilover kit S14 (part number D-14-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Nissan Silvia, 200SX and 240SX on the S14 platform, model years 1995 to 1999. The spring rate is 6 kg/mm front and 4 kg/mm rear.
This 3-way adjustable kit is built for competitive track work, long sessions and demanding drift use, where ordinary dampers start to give up after a few laps.
In the ZX, BC Racing combines the DS and ER series: upright monotube dampers with a dual piston and an external reservoir. As a result, the damping stays stable, even when the oil gets really hot after a long stint.
The spring rate is 6/4 kg/mm. You adjust the low-speed compression in 20 clicks, the high-speed compression in 12 clicks and the rebound in 30 clicks, all three independently of each other.
Key benefits
- 3-way adjustable: low-speed compression, high-speed compression and rebound adjustable separately.
- External reservoir: more oil volume and consistent damping during long sessions.
- Dual piston: finer control over how the damper responds to fast and slow movements.
- Digressive damping: the body stays flat, while the wheels can move over kerbs.
- Race oil with an ultra-high viscosity index: keeps its properties even when it gets hot.
- Replaceable upper mount: with camber plates, rubber top mounts optional.
- Spring rate 6/4 kg/mm: a versatile base for the S14 on circuit and drift track.
- Rebuildable: the kit can be rebuilt and set up again.
Suitable for
Nissan Silvia, 200SX and 240SX on the S14 platform, model years 1995 to 1999
- Competitive track driving and time trials

Fitting and delivery
Position the reservoirs so that the lines stay clear of the wheels and brake lines at full compression and full extension. Start with the BC Racing base setting, and have the wheel alignment redone after adjusting the ride height. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the kit is temporarily out of stock, you can still order: we will keep you informed of the delivery date.
Three separate adjustments mean you no longer have to choose between grip over the kerbs and a flat car: with the ZX you set both separately.
Why choose this ZX coilover kit S14?
If your S14 spends more time on the circuit than in the car park, you want a suspension that grows with your driving style. The ZX gives you enough adjustment options to fine-tune for each track, each tyre and each weather condition, without the damping fading after a few laps.

Frequently asked questions
What is the difference between the BC Racing ZX and ZR for the Nissan S14?
The ZX uses upright dampers and a replaceable upper mount; the ZR is made for competitive motorsport, with inverted dampers on MacPherson strut axles and upright ones on double wishbones. Both are 3-way adjustable with an external reservoir. The ZX coilover kit S14 is the choice if you want to combine the DS base with the reservoir technology of the ER.
Is the BC Racing ZX coilover kit S14 suitable for driving on the road?
Yes, that is possible, but the kit is made for circuit and drift. Noise that comes with track-focused dampers is not covered by the warranty.
What is the delivery time of this BC Racing ZX coilover kit for the Nissan S14?
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 let you know when the kit arrives.
