Description
Toyota ZN8 GR86 (22+) BC Racing ZX coilover kit 5/5 kg/mm
The BC Racing ZX coilover kit GR86 (part number C-185-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Toyota GR86 (ZN8), from model year 2022. The spring rate is 5 kg/mm front and 5 kg/mm rear.
The ZX series combines the construction of the DS with the external reservoir of the ER and adds a third adjustment. You adjust the low-speed compression in 20 clicks, the high-speed compression in 12 clicks and the rebound in 30 clicks. This makes the kit suited to competitive track work, long sessions and demanding drifting with the GR86.
The upright monotube dampers have two pistons and a digressive characteristic and are filled with racing oil with a very high viscosity index. The upper mount is replaceable; camber plates are fitted on suitable kits and rubber top mounts are optional.
Key benefits
- 3-way adjustable: 20 clicks of low-speed compression, 12 clicks of high-speed compression and 30 clicks of rebound.
- External reservoir: dual-piston monotube dampers with a separate reservoir.
- Digressive damping: tight control of slow body movements.
- Racing oil: with a very high viscosity index.
- Replaceable upper mount: camber plates on suitable kits, rubber top mounts optional.
- Spring rate 5/5 kg/mm: equal spring stiffness front and rear for the GR86.
- For drift and track: made for long sessions and demanding drifting.
- Rebuildable: the dampers can be rebuilt.

Fitting and delivery
The kit is vehicle-specific and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. After setting the ride height, have the wheel alignment set up for your use, for example a drift or track setup. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. BC Racing out of stock? You can still order the kit and we will let you know the delivery date.
The BC Racing ZX kit C-185-ZX for the Toyota GR86 is 3-way adjustable: 20 clicks of low-speed compression, 12 clicks of high-speed compression and 30 clicks of rebound.
Why choose this ZX coilover kit GR86?
With three separate adjustments you can fine-tune the GR86 in detail: the low-speed compression mainly affects body roll and dive, the high-speed compression affects kerbs and bumps. That makes the ZX a good match for long track sessions and demanding drifting. BC Racing UK also lists this ZX for the GR86 as a recommended kit.

Frequently asked questions
What is the difference between the BC Racing ZX and ER coilover kits for the Toyota GR86?
The ZX is 3-way adjustable, the ER 2-way. With the ZX you set not only the rebound but also the low-speed and high-speed compression separately. For competitive track work and demanding drifting, the ZX coilover kit GR86 therefore gives you more setup options.
Does the BC Racing ZX coilover kit fit every Toyota GR86 ZN8?
Yes, BC Racing has the ZX kit C-185-ZX for the Toyota GR86 (ZN8) from model year 2022. That GR86 was built exclusively as a rear-wheel drive coupe. For the GT86 (ZN6) and the Subaru BRZ (ZD8) you use a different kit.
Is the BC Racing ZX coilover kit for the GR86 suitable for drifting?
Yes, BC Racing explicitly names demanding drifting as an application of the ZX series, alongside competitive track work and long sessions. With the 3-way adjustment you tune the damping to the drift track.
How quickly is the BC Racing ZX coilover kit for the Toyota GR86 available?
The ZX is available in 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily has it out of stock, you can still order and we will keep you informed of the delivery date.
