KW DDC ECU Electronic Coilover Kit - BMW Z4 sDrive M40i G29 / Toyota GR Supra A90 (2019-2027)
The Z4 G29 and A90 Supra share a platform, a powertrain, and factory adaptive dampers that actually matter to the way these cars feel. Replacing them with static coilovers has always meant giving up the suppleness that makes either car livable on the street.
KW DDC ECU solves that completely. This kit replaces the factory adaptive dampers on both the Z4 sDrive M40i and the GR Supra A90, then plugs directly into the factory EDC harness. Comfort mode stays comfortable. Sport feels sharper. The KW damper valving takes over, but the factory controls still run the show. One coilover kit, properly integrated, for both the roadster and the coupe.
