Key Features:

The KW DDC ECU Coilovers combine advanced engineering with user-friendly technology to elevate your vehicle’s suspension capabilities:

  • Plug & Play installation with direct replacement of factory electronic struts using original vehicle connectors
  • Maintains full compatibility with OEM electronic damper controls and on-board suspension computer
  • Dynamic Damping Control (DDC) technology allows seamless switching between Comfort, Normal, and Sport modes
  • Individually adjustable ride height within tested and approved parameters for a tailored stance

  • Hand-built and dyno-tested at KW’s headquarters in Fichtenberg, Germany, ensuring quality and performance
  • Limited Lifetime Warranty with unlimited mileage for long-term peace of mind

Construction & Design:

KW’s DDC coilovers are engineered with premium materials and meticulous craftsmanship. The struts feature INOX-LINE stainless steel construction, which guarantees 100% corrosion resistance and an unlimited lifespan, even with frequent ride height adjustments. The composite spring perches utilize a friction-optimized polyamide material combined with stainless steel inserts, preventing oxidation while maximizing structural integrity. Elastomer bump stops are designed to absorb dynamic loads while protecting suspension components from contaminants, ensuring durability and consistent ride quality.

Every coilover is hand-assembled and individually serial-numbered, reflecting KW’s commitment to precision and quality control. Extensive stress testing and dyno validation confirm that each unit meets or exceeds OEM standards, delivering reliable performance on both road and track.

The factory electronic struts are removed and replaced with the KW INOX-LINE coilover struts, which connect directly to the vehicle’s original wiring harness using the supplied plugs. This plug-and-play design preserves all factory electronic suspension functions and controls, allowing the driver to continue using the OEM damper adjustment buttons inside the vehicle.

The coilovers are specifically engineered for the 2020–2023 Toyota GR Supra (A90) and BMW Z4 sDrive M40i (G29) models equipped with electronic dampers, ensuring perfect fitment and optimal performance.
