How to build your own sim racing steering wheel – a guide to Simline DIY parts

Building a custom sim racing steering wheel is a popular choice among advanced sim racers who want hardware perfectly tailored to their needs — in terms of button layout, materials and compatibility with a specific Direct Drive base. At Simline you'll find a complete ecosystem of parts for exactly this kind of project.

Where to start with a DIY steering wheel build

Every DIY steering wheel requires a few key components. Here's what you need at each stage of the build:

USB controller – the brain of the wheel, registering signals from every button and encoder. The most popular choices are the Simline X36 Ultimate (36 inputs), the BU0836A 12-bit (the proven DIY community standard), and the DSD BLU32 BLE with Bluetooth wireless communication.
Rotary encoders – for engine maps, brake bias or DRS. Recommended options: ELMA E33 (professional-grade quality), Bourns PEC11H and CTS 288T.
Funky Switch – a multi-function 5-axis switch (4 directions + push), an essential component of any modern racing wheel. Available versions: ALPS RKJXT1F42001 and the complete 7-in-1 Multiswitch kit with aluminium knob.
Aluminium knobs – fitted over encoder and funky switch shafts. Several shapes are available to suit different component types: No.1, No.2, No.3, No.5.
Spiral coil cable – connects the wheel to the base, allowing free rotation without cable tangling. Available in USB-A Simline and micro USB versions.
Quick release – for mounting the wheel on the Direct Drive base shaft. Choose the right standard for your base: SQR for Simucube, QR50/70 for Simagic, QR for MOZA or Asetek QR.

Is DIY the right choice for me?

Building a custom steering wheel from DIY parts gives you complete control over the final product — you can create a GT, rally, F1-style or even flight sim wheel with exactly the control layout you need. It does, however, require some technical knowledge of electronics and soldering. If you prefer a ready-to-use solution, check out our button plates or complete sim racing steering wheels.
