BMW E90/E92 M3 Sedan/Coupe with EDC (06-13) BC Racing ZX coilover kit 6/12 kg/mm

The BC Racing ZX coilover kit M3 E92 EDC (part number I-13-ZX) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M3 E90 and E92 with EDC (electronic damper control), model years 2006 to 2013; according to BC Racing, an EDC delete kit is required. The spring rate is 6 kg/mm front and 12 kg/mm rear.

According to BC Racing, the ZX brings the DS and the ER together in a 3-way kit with external reservoir. It is made for competitive track work, long sessions and demanding drifting, and this version is intended for the M3 E90 and E92 with EDC.

The upright monotube with double piston lets you set 20 clicks of low-speed compression, 12 clicks of high-speed compression and 30 clicks of rebound. The springs are 6 kg/mm front and 12 kg/mm rear. For an M3 with EDC, according to BC Racing, an EDC delete kit is required, and BC Racing does not sell it.

Fitting and delivery

The kit is vehicle-specific and replaces the original EDC dampers and springs. We recommend having it fitted by a mechanic with experience of motorsport suspension, also for the reservoirs. Please note: according to BC Racing UK, an EDC delete kit is required on an M3 with EDC. BC Racing does not sell that kit; it is therefore not included with this coilover kit and must be purchased separately. After setting the ride height, a new wheel alignment is needed. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing does not have the kit in stock, you can still order and we will let you know when it comes in.

The BC Racing ZX kit I-13-ZX for the BMW M3 E90 and E92 with EDC is 3-way adjustable and has springs of 6 kg/mm front and 12 kg/mm rear.

Why choose this ZX coilover kit M3 E92 EDC?

On the M3, the ZX gives you three separate settings, so you tune slow and fast movements independently of each other. That is useful in long sessions on track and when drifting, where the car has to keep responding under changing conditions. Bear in mind the EDC delete kit, which you need in addition to the kit.

Frequently asked questions

What is the difference between the BC Racing ZX and ZR coilover kits for the M3 E92 with EDC?

Both are 3-way adjustable with 20/12/30 clicks and an external reservoir, but the ZX has springs of 6/12 kg/mm and the ZR of 8/16 kg/mm. The ZR is made for competitive motorsport and, according to BC Racing, needs periodic greasing; the ZX is also intended for long sessions and drift.

How do I know whether I need the BC Racing ZX kit I-13 or I-39 for my M3 E90/E92?

That depends on whether your M3 has EDC: with EDC it is the I-13-ZX, supplemented by an EDC delete kit; without EDC the I-39-ZX. An EDC button on the centre console usually indicates EDC; if you are not sure, contact us.

Do I get an EDC delete kit with the BC Racing ZX coilover kit for the M3 with EDC?

No, that kit is not included and BC Racing does not sell it either. According to BC Racing UK, you do need it with the ZX coilover kit M3 E92 EDC, so you arrange it separately.

Does the BC Racing ZX coilover kit I-13 also fit the M3 E93 Convertible?

No. This kit is released for the M3 E90 Sedan and the M3 E92 Coupe with EDC; for the M3 Convertible E93, BC Racing has separate kits.

What is the delivery time of the BC Racing ZX coilover kit for the M3 with EDC?
