BC Racing DS Series Coilover - 88-93 3 Series (51mm Front Strut - Weld In) EXTREME E30 (WELD IN)

Item SKU: I-07-DS-DA

This BC Racing DS Series coilover kit is cataloged for the 1988-1993 BMW 3 Series with 51mm front struts, in the EXTREME E30 (WELD IN) configuration. The 51mm callout is the front strut diameter, and this is the weld-in version listed specifically for that E30 fitment.

• DS damper design: BC Racing's digressive piston and damping curve add more damping force during low-speed chassis movement, where roll, brake dive, pitch, and quick transitions are felt most.
• Monotube shocks: The DS Series uses a monotube damper layout with satin-chrome shock bodies.
• Independent height adjustment: Ride height is adjusted separately from spring compression, so setting the car's height doesn't require using spring preload as the adjustment.
• E30-specific configuration: This kit is for 1988-1993 3 Series cars with 51mm front struts and the cataloged EXTREME E30 (WELD IN) setup. No guessing between strut diameters or mounting versions.
• Serviceable parts: DS Series coilovers are rebuildable, and BC Racing offers individual replacement components for the series.

For an E30 that sees technical roads or track time, this stuff is aimed at making the car easier to read when weight moves around. You get more support in the low-speed damper range without the higher-speed response feeling abruptly overdamped. No made-up drop figures or generic spring-rate claims here, just the specific 51mm front-strut, weld-in E30 configuration this SKU represents.
