Description

BMW E36 3 Series True Rear Sedan/Coupe/Convertible/Touring (92-98) BC Racing HM coilover kit 6/5 kg/mm

The BC Racing HM coilover kit E36 True Rear (part number I-30-HM) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW 3 Series E36 Sedan, Coupe, Convertible and Touring, model years 1992 to 1998, in True Rear version. The spring rate is 6 kg/mm front and 5 kg/mm rear.

The HM series brings together the inverted design of the RM and the reservoir technology of the ER in one kit. It is intended for drivers who use their E36 seriously on track and want to leave nothing to chance.

True Rear means that the E36 also gets a complete strut at the rear: the spring around the damper, instead of the separate spring and separate damper from the factory. The MacPherson front struts have an inverted dual-piston monotube. The external reservoirs, which contain the second piston, are connected by PTFE-coated braided steel lines.

The spring rate is 6/5 kg/mm and you set compression and rebound in 30 clicks each, independently of each other. The ride height is infinitely adjustable via the damper body.

Key benefits

• RM and ER in one kit: inverted design plus external reservoirs.
• 2-way adjustable: compression and rebound 30 clicks each, independent of each other.
• Braided steel lines: PTFE-coated, leading to the external reservoirs that hold the second piston.
• Inverted monotube at the front: on the MacPherson front struts of the E36.
• True Rear rear end: no more separate spring and damper, but a complete strut.
• Digressive damping: tight at slow movements, controlled at fast ones.
• Synthetic oil: made for heavy track loads.
• Camber plates: with rubber top mounts as an option.

Fitting and delivery

The kit is vehicle-specific and replaces the original dampers and springs. Decide in advance where the reservoirs and lines will go. Please note: BC Racing specifies that the body shell must be reinforced before fitting a True Rear kit. BC Racing advises periodic greasing of the HM series and recommends it less for road use than the BR, DS, ER or ZX. After setting the height, have the wheel alignment checked and reset. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the manufacturer is temporarily out of stock, you can still order and we will keep you informed.

The HM is what you get when BC Racing combines the inverted RM and the 2-way ER, and with True Rear it now fits the rear of the E36 too.

Why choose this HM coilover kit E36 True Rear?

On track you want to be able to tune the damping for each direction without sacrificing stability. The HM gives you that freedom with separate compression and rebound adjustment, and the True Rear rear axle means you are no longer tied to a separate spring at the rear. This way you set up the E36 all round like a real track car.
