Hardware – Expansion of a Driving Simulator [by Gregg Lagnese]

Expansion of a Driving Simulator [by Gregg Lagnese]

Gregg Langnese has updated his impressive sim rig and after his famous ” Anatomy of a driving simulator, now brings us Expansion of a driving Simulator.

This video details the concepts and design decisions used in developing the dashboard and 8-speed shifter expansion to the DIY Driving Cockpit.
It details the design elements, reasoning, and features of the design in an effort to assist other DIY project builders who are developing their own version of my Simulator Sled design.
The basis of the design ergonomics were derived from an actual 2005 BMW M3.

The overview of the driving cockpit can be found at the original video Here.

This expansion design is self-contained and drop in ready. It includes a physical dashboard and 8-speed shifter.
The entire construction cost of the expansion was approximately $800 and the details are described in this video.
Total build time was approximately 2 weeks.
