Upgrade the suspension on your 1992–2000 Lexus SC300 or SC400 RWD with the BC Racing DS Series Coilovers. Engineered for the JZZ30 platform, the DS Series combines BC Racing's proven monotube damper design and extensive adjustability with proprietary digressive piston technology for enthusiasts seeking sharper response, improved chassis control, and an adjustable lowered stance.

The digressive piston generates increased damping force at lower piston velocities to better control body roll, pitch, brake dive, and rapid weight transfer. At higher piston velocities, the damping curve becomes more linear to help maintain compliance over bumps and uneven surfaces. Combined with 30-click damping adjustment, full-length ride height adjustment, and application-specific spring rates, the DS Series delivers a highly tunable suspension package for street and performance-oriented SC builds.

Digressive Piston Valving: BC Racing's proprietary digressive piston increases low-speed damping force for sharper chassis response during cornering, braking, acceleration, and quick transitions.

30-Click Damping Adjustment: Simultaneously adjusts compression and rebound through 30 settings, allowing you to fine-tune suspension behavior for your driving style and conditions.

Full-Length Ride Height Adjustment: Allows ride height to be adjusted independently from spring preload, helping preserve suspension travel and damper performance.

Monotube Damper Design: Single-cylinder construction provides consistent damping performance and effective heat dissipation during demanding driving.

Chassis-Specific Spring Rates: Features 12 kgf/mm front and 6 kgf/mm rear spring rates matched to the SC300 and SC400 platform.

Satin Chrome Shock Bodies: Distinctive satin chrome damper bodies visually differentiate the DS Series from BC Racing's BR Series.

Swift Spring Option: Compatible with optional 62mm ID Swift Springs for enthusiasts looking to further customize their suspension configuration.
