Description

BMW E90/E92 M3 Sedan/Coupe without EDC (06-13) BC Racing BR coilover kit 6/10 kg/mm

The BC Racing BR coilover kit M3 E92 (part number I-39-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M3 E90 and E92 without EDC, model years 2006 to 2013. The spring rate is 6 kg/mm front and 10 kg/mm rear.

For an M3 E90 or E92 without EDC, this is BC Racing’s all-round coilover kit. The BR series is made for the road and leaves room for a track day or autocross, without you having to go straight to a competition kit.

You get monotube dampers with a linear piston, 30 clicks of damping adjustment and a ride height that you set independently of the spring preload. Front and rear you get springs of 6 and 10 kg/mm.

Key benefits

• All-round for road and track: usable every day and ready for a track day or autocross.
• Ride height independent of spring preload: lower the M3 while the spring keeps its preload.
• 30-click damping adjustment: compression and rebound together, per damper.
• Monotube with linear piston: predictable handling that is easy to set up.
• Spring rate 6/10 kg/mm: the same as the DS kit for the M3 without EDC.
• Pillowball top mounts or camber plates at the front: rubber or the original mounting at the rear.
• Patented concave lower lock ring: holds the set height.
• Rebuildable: the dampers can be rebuilt.

Suitable for

BMW M3 E90 Sedan (2006 to 2013) and M3 E92 Coupe (2007 to 2013) without EDC (electronic damper control); not for the M3 with EDC, the M3 Convertible E93 and the non-M 3 Series

• Daily driving with a tighter and lower M3
• The occasional track day or autocross
• Lowering while keeping the spring preload

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. On some cars the pillowball top mount at the front requires a small modification to the upper mounting; if in doubt, contact us. According to BC Racing UK, a plug-in kit may be needed with this version to prevent an error message; feel free to ask us for advice. After setting the ride height, have the wheel alignment set again. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily has the kit out of stock, you can still order and we will let you know the delivery date.

For the BMW M3 E90 and E92 without EDC, BC Racing supplies the BR kit I-39-BR-RA with 6 kg/mm front and 10 kg/mm rear.

Why choose this BR coilover kit M3 E92?

With the BR you give your M3 without EDC a suspension you set up yourself: you choose the height independently of the spring preload and adjust the damping in 30 steps, from calm on the motorway to tight on a track day. Because the dampers are rebuildable, you can have the kit rebuilt after years of use.

Frequently asked questions

What is the difference between the BC Racing BR and DS coilover kits for the BMW M3 E92 without EDC?

The BR has a linear piston, the DS a digressive piston that damps more firmly during slow body movements. For the M3 without EDC, both have springs of 6/10 kg/mm. The BR coilover kit M3 E92 suits mainly road use, the DS suits those who go on track more often.

How do I choose between the BC Racing BR coilover kit I-39 and I-13 for my M3 E90 or E92?

That depends on whether your M3 has EDC (electronic damper control): without EDC, this I-39-BR-RA is the right kit; with EDC you choose the I-13-BR-RA, for which BC Racing also specifies an EDC delete kit that BC Racing does not sell. You can usually recognise an M3 with EDC by the EDC button on the centre console; if in doubt, we will check it with your chassis number.

Does the BC Racing BR coilover kit I-39 fit the M3 Sedan, Coupe and Convertible?

It fits the Sedan and Coupe, but not the Convertible. BC Racing releases the kit for the M3 E90 Sedan (2006 to 2013) and the M3 E92 Coupe (2007 to 2013) without EDC. For the M3 Convertible E93, BC Racing has separate kits.

What is the delivery time of the BC Racing BR coilover kit for the M3 without EDC?

The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the kit is temporarily sold out, you can still order it and we will keep you informed.
