The BC Racing BR-Series coilover suspension kit offers versatile adjustment options, high performance, and reliable operation for both street and track use. The monotube design and large-capacity shock absorber ensure consistent and predictable damping even during aggressive driving.
The shock absorber uses a 46 mm piston in a 53 mm body, which increases oil volume and reduces the effect of temperature on damping performance. A larger oil volume helps maintain consistent damping even under prolonged stress.

Vehicle: BMW 3-series E36
Features:
- 30-level damping adjustment (combined compression and rebound)
- Ride height adjustment via the lower mount – maintains full shock absorber travel
- Camber-adjustable aluminum pillowball top mounts (front axle)
- Monotube design for efficient heat management
- Nitrogen-pressurized shock absorbers to ensure consistent damping
- Adjustable spring perch and corner weighting possible
- Bearing-mounted upper spring perch reduces friction and improves steering feel
- Dust boots to protect shock absorber seals
- Patented locking ring prevents height adjustment from loosening
Performance and adjustability
Ride height adjustment:
The ride height is adjusted from the lower mount of the shock absorber, allowing for a wide adjustment range without affecting spring preload or the shock absorber's operating range.
Damping adjustment:
The 30-level adjustment allows for fine-tuning of the suspension for various uses. By adjusting the damping of the front and rear axles, driving behavior, such as understeer and oversteer, grip, and weight transfer, can be influenced.
Corner weight:
The adjustable spring perch allows the car to be balanced so that the load is evenly distributed to all wheels, improving grip, driving stability, and cornering speed.
