BMW E90/E92 3 Series True Rear Sedan/Coupe RWD (05-11) BC Racing BR coilover kit 5.5/6 kg/mm

The BC Racing BR coilover kit E90 E92 True Rear (part number I-118-BR-RH) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW 3 Series E90 Sedan and E92 Coupe with rear-wheel drive, excluding the M3, model years 2005 to 2011, in True Rear version. The spring rate is 5.5 kg/mm front and 6 kg/mm rear.

With the True Rear kit the spring sits around the damper at the rear, so you have a complete strut at the rear; with the standard I-03 kit the spring and damper remain separate at the rear, as from the factory.

The BR series is the all-rounder from BC Racing: monotube dampers with a linear piston, 30-click adjustment and a ride height that you set independently of the spring preload. This kit has pillowball top mounts or camber plates front and rear, and springs of 5.5 kg/mm front and 6 kg/mm rear.

Key benefits

• True Rear: a complete strut at the rear as well, with the spring around the damper.
• Pillowball top mounts front and rear: or camber plates, for a direct connection all round.
• Ride height independent of spring preload: lowering without changing the spring preload.
• 30-click damping adjustment: compression and rebound together, per damper.
• Monotube with linear piston: predictable and easy to set up.
• Spring rate 5.5/6 kg/mm: for the True Rear setup of the E90 and E92.
• Patented concave lower lock ring: holds the set height.
• Rebuildable: the dampers can be rebuilt.

Suitable for

BMW 3 Series E90 Sedan and E92 Coupe with rear-wheel drive, model years 2005 to 2011, in True Rear version; not for the M3 and not for the xDrive (xi) with four-wheel drive. For the E91 Touring and E93 Convertible, BC Racing has separate kits (I-17).

• Road with the occasional track day
• Drivers who also want a complete strut at the rear
• E90 and E92 cars getting pillowball top mounts all round

Why choose this BR coilover kit E90 E92 True Rear?

With True Rear the spring also sits around the damper at the rear, so the E90 or E92 is built the same way all round. Together with the pillowball top mounts front and rear, you get a direct, easily adjustable 3 Series that remains usable on the road. Do take into account the body shell reinforcement that BC Racing specifies before fitting.
