BMW E93 M3 Convertible with EDC (08-13) BC Racing BR coilover kit 6/10 kg/mm

The BC Racing BR coilover kit M3 E93 EDC (part number I-153-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M3 E93 Convertible with EDC, model years 2008 to 2013; according to BC Racing, an EDC delete kit is required. The spring rate is 6 kg/mm front and 10 kg/mm rear.

The BR series is BC Racing’s all-round coilover kit, intended for a car that is driven mainly on the road and does the occasional track day or autocross. For the M3 E93 Convertible with EDC you get monotube dampers with a linear piston, 30-click damping adjustment and a ride height that you set independently of the spring preload.

EDC is the electronic damper control that BMW offered as an option on the M3. This coilover kit takes the place of those EDC dampers, and BC Racing specifies an EDC delete kit for this. That kit is not part of the kit and is not supplied by BC Racing.

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs. We recommend having it fitted by an experienced mechanic. According to BC Racing, an M3 E93 with EDC requires an EDC delete kit; it is not included in the kit and BC Racing does not supply it, so arrange it in advance. On some cars the pillowball top mount at the front requires a small modification to the upper mounting; if in doubt, contact us. After adjusting the ride height, have the wheel alignment reset, because camber and toe change as well. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing is temporarily out of stock of the kit, you can still order and we will let you know the expected delivery date.

For the BMW M3 E93 Convertible with EDC, BC Racing supplies the BR kit I-153-BR-RA with 6 kg/mm front and 10 kg/mm rear; an EDC delete kit is required.

Why choose this BR coilover kit M3 E93 EDC?

An M3 Convertible is made to be enjoyed, but on worn dampers it feels sluggish on turn-in and under braking. With this kit you decide the ride height yourself, adjust the damping in 30 steps and keep a car that remains perfectly usable for long drives. That makes the BR the logical entry point if you want to replace the EDC dampers with an adjustable coilover kit.

Frequently asked questions

Does the BC Racing BR coilover kit I-153 fit every BMW M3 E93 Convertible?

No, only the M3 E93 Convertible with EDC from model years 2008 to 2013, in combination with an EDC delete kit. If your E93 does not have EDC, the BR kit I-154-BR-RA is the right choice. For the M3 E90 Sedan and E92 Coupe, BC Racing has separate kits with their own part numbers.

What is the difference between the BC Racing BR and RM coilover kits for the BMW M3 E93 with EDC?

The BR is made for the road with the occasional track day, the RM for track days, hill climbs and tarmac rally. The RM uses a digressive piston and fully synthetic oil, but requires periodic greasing and is less recommended by BC Racing for road use. If you drive your Convertible mainly on the road, the BR coilover kit M3 E93 EDC is the most suitable choice.

Is the EDC delete kit included with the BC Racing BR coilover kit for the BMW M3 E93?

No, the EDC delete kit is not included in the kit and is not supplied by BC Racing. BC Racing does specify the kit for an M3 E93 with EDC, so make sure you have it before the kit is fitted. If you have questions about the installation, feel free to contact us.
