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

The BC Racing DS coilover kit M3 E92 EDC (part number I-13-DS-DA) 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.

For an M3 E90 or E92 with EDC that goes on track more often, the DS is BC Racing’s track-focused choice. The monotube damper with digressive piston damps more firmly during slow body movements between 0 and 50 mm/s.

At the rear, the 12 kg/mm spring is firmer than on the BR kit for this car; at the front it is 6 kg/mm. You adjust the damping in 30 clicks and the ride height independently of the spring preload. For the M3 with EDC, BC Racing specifies an EDC delete kit, which BC Racing does not sell itself.

Key benefits

• Digressive piston: firmer damping during slow movements from 0 to 50 mm/s.
• Spring rate 6/12 kg/mm: firmer at the rear than the BR kit for the M3 with EDC.
• 30-click adjustment: compression and rebound together, per damper.
• Height independent of the spring preload: lower the car without changing the preload on the springs.
• Pillowball top mounts or camber plates at the front: rubber or the original mounting at the rear.
• Satin chrome damper body: the finish of the DS series.
• Concave lower lock ring: the set height stays locked in place.
• Rebuildable: the dampers can be rebuilt.

Fitting and delivery

This coilover kit is specific to the M3 E90 and E92 with EDC and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. 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. On some cars the pillowball top mount at the front requires a small modification to the upper mounting; if in doubt, contact us. After setting the height, a new wheel alignment is needed. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the manufacturer does not have it in stock, you can still order and we will let you know when the kit has arrived.

The BC Racing I-13-DS-DA is the DS coilover kit for the BMW M3 E90 and E92 with EDC, with 6 kg/mm front, 12 kg/mm rear and a digressive monotube damper.

Why choose this DS coilover kit M3 E92 EDC?

Choose the DS if your M3 with EDC is regularly on track. The digressive piston and the firmer rear spring keep the body calmer during quick changes of direction, while you fine-tune the damping in 30 clicks. Alongside the kit, do budget for an EDC delete kit.

Frequently asked questions

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

The DS has a digressive piston and springs of 6/12 kg/mm; the BR has a linear piston and 6/10 kg/mm. The DS is track-focused, the BR is made for the road with the occasional track day. If you often drive on track, the DS coilover kit M3 E92 EDC is the better fit.

Should I take the BC Racing DS kit I-13 or I-39 for my BMW M3 E90/E92?

The EDC decides: if your M3 has electronic damper control, take the I-13-DS-DA, otherwise the I-39-DS-DA. You can usually recognise the EDC version by an EDC button on the centre console. For the I-13, BC Racing specifies an EDC delete kit; if you are unsure about your car, contact us.

Does BC Racing supply an EDC delete kit with the DS coilover kit for the M3 with EDC?

No, BC Racing does not sell an EDC delete kit. According to BC Racing UK, such a kit is required with this kit, so you need to arrange it separately.

Is the BC Racing DS coilover kit I-13 suitable for the M3 E93 Convertible?

No. BC Racing only releases this kit for the M3 E90 Sedan and the M3 E92 Coupe with EDC. For the M3 Convertible E93 there are separate BC Racing kits.
