Sedan / Coupe | Rear-Wheel Drive (RWD)
Spring Rates: 5.5 kg/mm Front / 8 kg/mm Rear
Coilover Type: RA (Weld-In Front, Rear Spring Separated)
BC Racing BR Series coilovers for the BMW 3 Series E30 (1982–1991) with 51 mm front struts (weld-in) are engineered to improve handling precision, chassis control, and ride height adjustability while maintaining a usable ride for road-driven classic BMW builds.
This kit uses a weld-in front strut design to suit the E30’s front suspension layout and provides modern monotube damper performance with wide adjustability. At the rear, the setup retains the separate spring and damper configuration, meaning the rear spring remains separate from the shock absorber, matching the original rear suspension architecture of the E30.
The 5.5 / 8 kg/mm spring rate combination is selected to suit the E30 chassis for a performance-focused setup, improving stability, reducing body roll, and delivering more responsive handling. The BR Series remains more than capable for fast road and track day use, while still keeping enough ride civility for longer journeys and everyday driving.
As part of BC Racing’s proven BR Series, this suspension provides a reliable and versatile upgrade for E30 owners seeking a sharper, more controlled driving feel with full adjustability.

Driving Characteristics
The BR Series improves the E30’s driving behaviour by sharpening front-end response and increasing overall chassis control. The rear separated spring layout keeps the suspension behaviour predictable and consistent with the E30’s OEM architecture, while the damping control and ride height adjustability significantly modernise the handling feel.
This setup suits drivers who want a lower stance and improved control for spirited driving, with the flexibility to fine-tune damping for road or track use.
