Description

BMW E36 M3 True Rear (92-99) BC Racing RM coilover kit 6/6 kg/mm

The BC Racing RM coilover kit E36 M3 True Rear (part number I-120-RM-MA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW E36 M3, model years 1992 to 1999, in True Rear version. The spring rate is 6 kg/mm front and 6 kg/mm rear.

The kit is made for M3 drivers who take track days, hill climbs or tarmac rally seriously, and turns the rear into a complete strut: the spring sits around the damper, whereas the M3 has a separate spring and a separate damper at the rear from the factory.

At the front, BC Racing uses an inverted monotube on the MacPherson struts in the RM series. The damping is digressive and is provided by fully synthetic oil with a very high viscosity index. Camber plates come as standard with suitable kits.

With 6/6 kg/mm the spring ratio is the same front and rear, and you adjust the damping in 30 clicks. The ride height is infinitely adjustable via the damper body, all round.

Key benefits

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs; the separate springs and dampers at the rear make way for the coilovers. Please note: BC Racing specifies that the body shell must be reinforced before fitting a True Rear kit. After setting the height, a new wheel alignment is required, because camber and toe change with it. BC Racing advises periodic greasing of the RM series and recommends it less for road use than the BR, DS, ER or ZX. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. No stock at the manufacturer? You can still order, and we will keep you informed.

Inverted at the front, a complete strut at the rear: the RM turns the E36 M3 into a car you can set up all round for the rally stage and the circuit.

Why choose this RM coilover kit E36 M3 True Rear?

An M3 that works hard on the circuit or during a hill climb deserves suspension that is just as serious. The RM combines the inverted design with digressive damping, and thanks to True Rear you adjust the rear just as precisely as the front.

Frequently asked questions

What does the BC Racing RM True Rear change on my E36 M3?
