Product Details

RS-R Down Sus lowering springs for the 2001-2006 Lexus LS430 (UCF30) drop the car into a cleaner, more purposeful stance while tightening body roll and sharpening turn-in on everyday roads. Each set is engineered specifically for this LS430 chassis, so drop, spring rate and factory damper tune stay in balance — the car sits where you want it and still drives like a daily.

Racing Studio-R built its first suspension in Osaka in 1972 and has been refining the Down Sus spring for more than fifty years. Each set is progressive-rate, cold-wound and heat-treated in-house in Japan, then matched to the factory shock valving and ride-height target of the specific chassis it bolts onto. Backed by RS-R’s 3-year / 50,000 km fatigue warranty.

Features

  • Progressive-rate coil tuned to the factory damper
  • Vehicle-specific drop and rate — no universal cuts
  • Cold-wound from high-grade SAE alloy steel
  • Powder-coated for long-term corrosion resistance
  • 3-year / 50,000 km RS-R spring-fatigue warranty
  • Made in Osaka, Japan
