A complete Zestek setup needs three things: the SCX button panel, the boss kit for your BMW, and an aftermarket steering wheel with a 6x70mm bolt pattern. The panel and boss kit are sold separately, and the wheel is not included. Check your exact chassis against the boss kit list. G8X M3 and M4 cars with ACC and Driver Assist are listed as their own application. The SCX is designed for cars running the factory ECU, and button mapping is set up through Zestek's Windows software over USB-C.

Fitting a Zestek hub means removing the factory steering wheel, which includes disconnecting the airbag, so installation by a professional is recommended. You will also need a Windows computer to configure the SCX panel with the supplied USB to USB-C cable. Zestek lists the boss kit for track use only, so check your state's rules before fitting it to a registered car.

Will I keep my factory steering wheel buttons with the Zestek SCX?
