KW Electronic Damping Cancellation Kit for BMW Z4 sDrive M40I (G29) - Toyota GR Supra (A90)

For those who want to install aftermarket coilover system, this is a must have.  Otherwise you will have a warning light on the dash and traction control can't be turned off.  

Cancellation kits eliminate persistent trouble codes that exist when upgrading a suspension on a vehicle with electronically regulated dampers.
KW is the only manufacturer that offers the solutions whereby the serial damper regulation is shut down and at the same time trouble code avoided. The functioning of the control unit remains completely intact.
