M4 GT3 Button Box Simracing mit VI-CWBB Velocitas

This M4-GT3 Cockpit Style Sim Racing Button Box is a DIY project for all BMW fans

The design is based on the button box from the M4 GT3 race car, as used in the cockpit or dashboard area This creates a particularly authentic layout for use in the rig

The box offers space for various buttons, toggle switches, and rotary encoders and is ideal for controlling functions such as brake bias, traction control, ABS, pit limiter, and more

The housing is compact, robust, and can be easily mounted via 75mm VESA to a sim racing rig and a monitor arm

For the button box, I used the VI-CWBB Simracing Button Box from Velocitas Imperium https://makerworld.com/de/models/493051-vi-cwbb-simracing-button-box#profileId-487543 The button box is then simply screwed into mine Feel free to check out Velocitas

These are the components I used

Melt-in nuts are required
