BMW E90/E92 M3 True Rear Sedan/Coupe (06-13) BC Racing BR coilover kit 6/6 kg/mm

The BC Racing BR coilover kit M3 E92 True Rear (part number I-117-BR-RH) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M3 E90 and E92, with or without EDC, model years 2006 to 2013, in True Rear version. The spring rate is 6 kg/mm front and 6 kg/mm rear.

With this True Rear kit from BC Racing, the M3 E90 or E92 also runs on a complete strut at the rear, with the spring around the damper instead of the separate spring and damper from the factory. The BR series is the all-rounder from BC Racing: made for the road, with enough in reserve for a track day or autocross.

The kit has monotube dampers with a linear piston, 30-click damping adjustment and a ride height that you set independently of the spring preload. Front and rear there are pillowball top mounts or camber plates, and the spring rate is 6 kg/mm all round.

Key benefits

• True Rear version: a strut with the spring around the damper at the rear as well.
• Ride height independent of spring preload: front and rear can be set separately.
• 30-click damping adjustment: compression and rebound in one action, per corner.
• Monotube with linear piston: a predictable response that is easy to set up.
• Pillowball top mounts front and rear: or camber plates, for a direct connection to the body.
• Spring rate 6/6 kg/mm: chosen by BC Racing for the M3 E90/E92 True Rear.
• Patented concave lower lock ring: holds the set height.
• Rebuildable: the dampers can be rebuilt.

• An M3 that is driven on the road and goes on track now and then

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs front and rear. We recommend having it fitted by an experienced mechanic. Please note: BC Racing specifies that with a True Rear kit the body shell must be reinforced before fitting. BC Racing UK also reports that pillowball top mounts can transmit noise to the body in this application. If your M3 has EDC, BC Racing says an EDC delete kit is required; it is not included in the kit and BC Racing does not supply it. After setting up, have the wheel alignment checked, because camber and toe change along with the ride height. 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.

The BC Racing BR kit I-117-BR-RH gives the rear axle of a BMW M3 E90 or E92 a complete strut, with 6 kg/mm springs and pillowball top mounts front and rear.

Why choose this BR coilover kit M3 E92 True Rear?

Anyone who wants to set up an M3 E90 or E92 seriously runs into the separate factory spring and damper at the rear. This True Rear kit solves that: at the rear too, you set the height independently of the spring preload. With the BR series the car remains very usable on the road, and you adjust the damping in 30 steps.

Frequently asked questions

Does the BC Racing BR True Rear kit I-117 fit the BMW M3 E90 Sedan and the M3 E92 Coupe?

Yes, the kit is intended for the M3 E90 Sedan and the M3 E92 Coupe from model years 2006 to 2013, with or without EDC. A car with EDC needs an EDC delete kit, which is not included in the kit. For the M3 E93 Convertible, BC Racing has separate kits (I-153 with EDC, I-154 without EDC).

What is the difference between the BC Racing BR and DS True Rear kits for the BMW M3 E92?

The BR has a linear piston and is made for the road with the occasional track day; the DS has a digressive piston and is more track-focused. Both have pillowball top mounts front and rear and the same 6/6 kg/mm springs. If your M3 is mainly driven on the road, the BR coilover kit M3 E92 True Rear is the logical choice.

What should I know about True Rear on the BC Racing BR coilover kit for the M3 E92?

With True Rear the spring also sits around the damper at the rear, whereas the M3 E90 and E92 have a separate spring and damper from the factory. BC Racing specifies that the body shell must be reinforced before fitting. If you want to keep the original rear setup, BC Racing has the I-13 (with EDC) and I-39 (without EDC) kits.

What is the delivery time of the BC Racing BR True Rear kit for the BMW M3 E92?
