Product Description

The KMP GT4-style wheel for BMW F8x M3 / M4 combines a carbon-fibre wheel with electronics designed to retain the specified BMW road-car functions. Eight buttons provide direct access to M1, M2, DTC, horn and cruise controls, plus two free-to-use outputs for additional equipment.

The two spare outputs can operate compatible external equipment such as a timer, radio or auxiliary light. They switch to ground through the supplied flying leads behind the slip ring. The installer must provide the equipment-specific wiring.

Eight-button position guide

Read these positions from the driver’s seat. The two middle buttons on each side are listed from top to bottom. This GT4 layout is different from the round Pro-Line wheel.

Button Position Function
SW1 Right bottom Free-to-use output
SW2 Right middle - lower M1
SW3 Right middle - upper DTC
SW4 Right top Horn
SW5 Left top Set speed
SW6 Left middle - upper Reset speed
SW7 Left middle - lower M2
SW8 Left bottom Free-to-use output

Labels and installation

Specify the function names for SW1 and SW8 when ordering if you require engraved labels. If no names are supplied, those label positions remain unengraved. The vehicle interface supports the listed BMW functions, while the two external outputs require their own installation.

Adapter choice

The fixed spacer is the base option. A curly-cable quick release detaches the wheel while keeping it tethered to the car. The integrated-connector quick release allows complete removal. Enter the exact vehicle model and year so the interface can be matched to the car.

FAQs

Can the wheel be fully removed?

The connector quick release allows complete removal. The curly-cable version remains tethered.

How are the free-to-use buttons connected?

They provide ground-switched outputs through flying leads behind the slipring. Wire your additional equipment to suit the application.

Can the spare buttons be labelled?

Enter both required labels before ordering. Engraving needs to be specified when the wheel is ordered.

What is the standard spacer?

KMP specifies a fixed 44 mm spacer for this GT4 wheel. The curly cable provides the electrical connection. A connector quick release removes the external tether when the wheel is detached.

Which are the free-to-use buttons?

SW1 at the right bottom and SW8 at the left bottom, viewed from the driver’s seat. The position table in Product Description identifies all eight controls.

Are the free-to-use outputs ready to power an accessory?

They provide switching to ground through supplied leads. The external equipment and its circuit must be wired to suit that equipment. Specify the intended function and engraving when ordering.
