Engineered specifically for the UCF20 chassis, the R-04-DS combines BC Racing's proven monotube damper architecture with proprietary digressive piston technology for sharper handling, precise suspension tuning, and an adjustable lowered stance.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe DS Series builds on BC Racing's BR Series platform with digressive valving that generates increased damping force at lower piston velocities. This helps control body roll, pitch, brake dive, and rapid weight transfer for a more responsive driving experience. At higher piston velocities, the damping curve remains more linear to help maintain compliance over bumps and uneven pavement. Combined with 30-click damping adjustment, full-length ride height adjustment, and chassis-specific 12K front and 8K rear spring rates, the DS Series provides a highly tunable suspension package for street and performance-oriented LS400 builds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDigressive Piston Valving:\u003c\/strong\u003e BC Racing's proprietary digressive piston increases low-speed damping force for sharper chassis response during cornering, braking, acceleration, and rapid weight transitions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e30-Click Damping Adjustment:\u003c\/strong\u003e Simultaneously adjusts compression and rebound through 30 settings, allowing suspension behavior to be fine-tuned for different roads and driving conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFull-Length Ride Height Adjustment:\u003c\/strong\u003e Allows vehicle height to be adjusted independently from spring preload, providing greater flexibility when dialing in stance and suspension travel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMonotube Damper Design:\u003c\/strong\u003e Single-cylinder construction provides consistent damping characteristics and effective heat dissipation during demanding driving.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMatched Spring Rates:\u003c\/strong\u003e Features 12 kgf\/mm front and 8 kgf\/mm rear spring rates matched specifically to the UCF20 LS400 platform.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSatin Chrome Shock Bodies:\u003c\/strong\u003e Distinctive satin chrome damper bodies visually differentiate the DS Series from BC Racing's BR Series.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSwift Spring Option:\u003c\/strong\u003e Compatible with optional 62mm ID Swift Springs using 62-178-X front and 62-228-X rear configurations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) BC Racing DS Series Coilover Kit\u003c\/li\u003e\n\u003cli\u003eFront coilover assemblies with matched springs\u003c\/li\u003e\n\u003cli\u003eRear coilover assemblies with matched springs\u003c\/li\u003e\n\u003cli\u003eAdjustment hardware where applicable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLexus LS400 RWD UCF20 (1995–2000)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBC Racing SKU: R-04-DS\u003c\/li\u003e\n\u003cli\u003eSeries: DS\u003c\/li\u003e\n\u003cli\u003eChassis: UCF20\u003c\/li\u003e\n\u003cli\u003eDrivetrain: RWD\u003c\/li\u003e\n\u003cli\u003eDamper Design: Monotube\u003c\/li\u003e\n\u003cli\u003eDamping Adjustment: 30-click simultaneous compression and rebound\u003c\/li\u003e\n\u003cli\u003eFront Spring: 62-200-12 kgf\/mm\u003c\/li\u003e\n\u003cli\u003eRear Spring: 62-220-8 kgf\/mm\u003c\/li\u003e\n\u003cli\u003eFront Spring Rate: 12 kgf\/mm\u003c\/li\u003e\n\u003cli\u003eRear Spring Rate: 8 kgf\/mm\u003c\/li\u003e\n\u003cli\u003eOptional Front Swift Spring: 62-178-X\u003c\/li\u003e\n\u003cli\u003eOptional Rear Swift Spring: 62-228-X\u003c\/li\u003e\n\u003cli\u003eShock Body Finish: Satin Chrome\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Notes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFits Lexus LS400 RWD UCF20 models from 1995–2000.\u003c\/li\u003e\n\u003cli\u003eBC Racing SKU: R-04-DS.\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for rear-wheel-drive applications.\u003c\/li\u003e\n\u003cli\u003eSwift Springs are optional and may be sold separately depending on configuration.\u003c\/li\u003e\n\u003cli\u003eVerify chassis code, drivetrain, model year, and selected spring configuration before ordering.\u003c\/li\u003e\n\u003cli\u003eProfessional installation is recommended.\u003c\/li\u003e\n\u003cli\u003eA four-wheel alignment is recommended after installation or ride height adjustment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhy Choose BC Racing DS Series Coilovers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBC Racing DS Series Coilovers are an excellent choice for UCF20 LS400 owners seeking sharper chassis response while retaining the adjustability needed for street and performance driving.
