Product Details

These RS-R Down Sus lowering springs fit the 2015-2023 Ford Mustang GT.

RS-R Down Sus lowering springs for the Ford Mustang GT lower the car, reduce body roll and sharpen turn-in. Each set is made for this car, so drop, spring rate and factory damper tune stay in balance.

Racing Studio-R built its first suspension in Osaka in 1972. 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
