I ordered a haldex controller for my Mk4 Golf build. Came a week before they said it would and works like a charm. Can really feel the difference on track.

Ordered one of Forbes Automotive's Haldex Controller, arrived in a timely fashion and looks a great bit of kit. Also asked for some custom CAN coding doing on some steering wheel buttons, and they were up to the challenge! Customer support was top notch too 👌
