BC Racing DS Series coilovers for the BMW 3 Series E30 (1982–1991) with 51 mm front struts are designed for drivers seeking a more performance-focused suspension setup with additional adjustability compared to the BR Series.
This kit is a direct bolt-on solution for vehicles equipped with 51 mm OEM front strut housings, requiring no welding or cutting. It is supplied with aluminium camber-adjustable pillowball top mounts on the front, allowing precise camber adjustment for improved front-end grip, sharper turn-in and better tyre contact under load.
At the rear, the suspension retains the OEM-style separate spring and damper layout, which is standard for the E30 chassis. The DS Series features firmer, more responsive damping characteristics than the BR Series, making it especially suitable for fast road driving, track days and performance-oriented builds.
The 5.5 / 8 kg/mm spring rate combination provides an excellent balance between control and usability, offering improved stability and reduced body roll while still maintaining reasonable comfort for road use.
As part of BC Racing’s advanced suspension range, the DS Series delivers increased precision, durability and adjustability for E30 owners who want more control over alignment and handling behaviour.
