Product Details

The D2 Racing PRO Series Lowering Springs deliver an aggressive stance while maintaining exceptional ride quality through advanced progressive rate spring technology. Engineered to reduce ride height and lower the center of gravity, these springs optimize handling characteristics and minimize body roll during hard cornering, heavy braking, and acceleration.

Key Features:

  • Progressive rate spring design provides comfortable ride under normal conditions while increasing stiffness during compression to control body roll
  • Lowers sedan/coupe models 1.7 inches front and 1.9 inches rear; hatchback models 2.0 inches front and rear
  • Manufactured from premium 55 chrome silicon steel for superior strength and durability
  • Cold wound and shot peened construction for increased stress relief and longevity
  • Produced in ISO 9001 and TUV certified facility ensuring consistent quality
  • Complete set includes all four lowering springs
  • Compatible with factory shocks or aftermarket performance dampers
  • Backed by lifetime warranty when purchased through authorized dealers

Unlike linear rate springs used by most competitors, D2 Racing's progressive rate design allows for a plush, comfortable ride during normal driving while automatically stiffening as the spring compresses. This intelligent design dramatically improves performance and handling by lowering the vehicle's center of gravity while maintaining daily drivability. Aftermarket shocks are highly recommended to maximize performance and longevity.
