KW DDC Plug & Play Coilover Kit (EDC) – Toyota GR Supra (A90 / A91) / BMW Z4 (G29)

OVERVIEW

DDC is KW's electronically adjustable coilover. Instead of reaching under the car with a screwdriver, damping is changed on the move — from the factory drive-mode switch or from the KW app — while the coilover still gives you the height adjustment a mechanical kit does.

The reason these kits are plug-and-play is that they use the wiring your car already has. The DDC damper plugs into the OE electronic damper connectors, so the factory EDC hardware is a requirement, not an obstacle. Because the circuit stays intact and the car keeps talking to a real damper, no ESC or EDC cancellation module is needed, and OE drive-mode damper control keeps working.

This is the kit for someone who genuinely uses both ends of the range: a comfortable commute and a firm setting for a back road or a track day, without a compromise setting in between. If your car does not have factory EDC, a DDC kit is the wrong product — look at the Variant 3 or Variant 4 kits instead.

TECH RESOURCES

Additional Parts Required

• Factory EDC / electronic dampers are mandatory. There is no non-EDC version of this part number.
• KW WLAN module 68510276 is required if you want smartphone control of the damping rather than drive-mode switch control only. See our KW ESC Cancellation Modules & Coilover Setup Tools listing.
• No ESC / EDC cancellation module is needed — the DDC damper replaces the OE damper on the same circuit.
• A corner-balance and a full four-wheel alignment are required after installation. Budget for both before the car is driven.

Installation

• Installation instructions: PDF.
• In brief: full strut-out replacement front and rear, the OE damper connectors plugged straight into the DDC units, ride height set inside KW's published range, then corner-balance and alignment.

Notes

• KW's own fitment chart (checked 2026-09-02) shows the BMW Z4 sDrive M40i (G29) fitment for this part number as 2020–2021 only, not through 2026 as previously listed. It also lists a 2.0L Toyota GR Supra Base trim (2021–2024) in addition to the 3.0L trims already shown; that row has been added.
• Fitment is published by engine family rather than by model year; confirm your car's engine code before ordering.
• KW publishes no product image for this part number.
• Price is for the item selected only; labor is not included.
