BMW E30 M3 weld-in (85-92) BC Racing BR coilover kit 6/8 kg/mm

The BC Racing BR coilover kit E30 M3 (part number I-24-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW M3 E30, model years 1985 to 1992, in BC Racing’s weld-in version, which requires welding for fitting. The spring rate is 6 kg/mm front and 8 kg/mm rear.

The E30 M3 is one of the best-known BMWs of the eighties, and its suspension deserves a kit that matches that character. The BC Racing BR series is the all-round choice, with linear monotube dampers, 30-click damping adjustment and a ride height that you set independently of the spring preload.

BC Racing makes a dedicated kit for the M3, separate from the kits for the regular E30 3 Series. This one is weld-in too: welding is required for fitting, and you should have that done by a specialist.

Key benefits

• Dedicated M3 kit: BC Racing makes a separate version for the E30 M3.
• Ride height independent of spring preload: lowering the M3 via the damper body.
• 30-click damping adjustment: compression and rebound together per damper.
• Linear monotube dampers: predictable, on track too.
• Spring rate 6/8 kg/mm: chosen for the M3 E30.
• Pillowball top mounts at the front: or camber plates, with rubber or the original mounting at the rear.
• Concave lower lock ring: patented, holds the set height in place.
• Rebuildable: the dampers can be rebuilt.
