BMW E36 3 Series True Rear Sedan/Coupe/Convertible/Touring (92-98) BC Racing ZX coilover kit 6/5 kg/mm

The BC Racing ZX coilover kit E36 True Rear (part number I-30-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW 3 Series E36 Sedan, Coupe, Convertible and Touring, model years 1992 to 1998, in True Rear version. The spring rate is 6 kg/mm front and 5 kg/mm rear.

It is the 3-way adjustable kit for an E36 that really has to work: long track sessions, competition and hard drift days. At the rear the E36 gets a complete strut, with the spring around the damper instead of the separate spring and separate damper the car has from the factory.

The ZX combines the basis of the DS with the reservoir technology of the ER. The result is an upright monotube with dual piston and external reservoirs, filled with racing oil with a very high viscosity index. You adjust low-speed compression, high-speed compression and rebound independently of each other.

The spring rate is 6/5 kg/mm. The ride height is continuously adjustable via the damper body, front and rear.

Key benefits

• 3-way adjustable: 20 clicks low-speed compression, 12 clicks high-speed compression and 30 clicks rebound.
• External reservoirs: made for long sessions at a high pace.
• Dual-piston design: the reservoir technology of the ER on a DS basis.
• True Rear: a complete strut at the rear as well, with the spring around the damper.
• Digressive characteristic: the body stays calm, the wheels keep following.
• Racing oil with a very high viscosity index: for damping that fades less when it gets hot.
• Replaceable upper mounting: with camber plates or optional rubber top mounts.
• Rebuildable: built to keep driving season after season.

Fitting and delivery

When fitting, the struts come out at the front and the separate springs and dampers at the rear. Plan in advance where you can place the reservoirs, and preferably have the kit fitted by an experienced mechanic. Please note: BC Racing specifies that the body shell must be reinforced before fitting a True Rear kit. After setting the height, have the wheel alignment set again. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If it is out of stock, you can still order; we will keep you informed.

Three settings per damper and a complete strut at the rear: with the ZX you decide how the E36 behaves, not the factory springs.

Why choose this ZX coilover kit E36 True Rear?

Anyone who seriously races an E36 quickly runs into limits with a 1-way kit. With the ZX you adjust the response to slow movements, hard impacts and rebound each separately, and with True Rear you do that on a complete strut at the rear as well. That keeps the car composed, even at the end of a long session.

Frequently asked questions

What is the difference between the BC Racing ZX True Rear and the standard ZX for the BMW E36?

This ZX coilover kit E36 True Rear turns the rear into a complete strut and comes with 6/5 kg/mm, while the standard ZX without True Rear (I-01-ZX) keeps a separate spring and separate damper at the rear and has 5.5/8 kg/mm.

BC Racing ZX or ER for the BMW E36, which suits better?

For competition and hard drift the ZX suits better, because it is 3-way adjustable. The ER is 2-way: compression and rebound 30 clicks each, independently of each other. The ZX goes a step further and splits the compression into low and high speed.

Is the BC Racing ZX coilover kit E36 True Rear suitable for the road?

Yes, it can be, but the ZX is made for the track and hard drift work. If you mainly drive on the road, a simpler kit is often the better choice.

Does this BC Racing ZX coilover kit E36 True Rear fit an E36 Touring or Convertible?

Yes. BC Racing releases this kit for all rear-wheel drive E36 versions except the M3 and the Compact: Sedan, Coupe, Convertible and Touring. BC Racing does specify that the body shell must be reinforced before fitting a True Rear kit.

What is the delivery time of this BC Racing ZX coilover kit for the BMW E36 True Rear?

The delivery time is normally 1 to 2 weeks, as long as the manufacturer has stock. Otherwise you can still order and we will let you know when it comes in.
