This kit is designed to fit to your wheel base and allow you to use your Fanatec steering wheels without modifying them.  Simply swap wheel rims as you would on a Fanatec wheel base. 

Now includes the base side QR2

  • Anodized aluminum case.
  • Brand new PCB version 7.2
  • Uses a USB C Cable held in place with our clamping mechanism
  • Full control of firmware, so I can develop this without relying on a third party
Build from the highest quality materials that are beautifully finished.

I have designed every part of the conversion kit personally. Everything is custom made either by me or for me.

Every kit is assembled by my hand in the UK


The Kit includes...

  • Version 7.20 SRM PCB
  • Aluminum casing
  • Coiled USB C cable
  • 6 x M5 45mm CAP bolts
  • 6 x M5 washers
  • 6 x M5 Nyloc nuts
  • Base Side QR2
  • 2mm Hex Key (From 14th August 2026)

This is the newest version of the base side conversion kit. 

Whats different 5.2x to 7.2x

  • PCB redesign using components from 7x conversion kit.
  • Has both USB terminal bock and Molex 4 pin plug for USB connection.
  • Uses 12 pin HY plug for better compatibility.

Whats different 7.2x to 7.21x

  • Uses removable / replaceable USB C Coiled cable as with the 7x kit.
  • Our cable clamping mechanism.

7.21x Black version from14th August 2026

  • USB cable is not fitted you will need a 2mm hex key to tighten the clamp. Hex key is included in the box.
  • Has a hole on the underside of the case to allow running a custom cable for a hidden USB connection.  This is DIY and no parts are included for this.

Fitting the conversion...

Fitting the conversion is easy. All the parts you need are included. You will need your own tools.
The latest 7.21x kit does not come with the USB cable fitted.
Please slide the USB C cable into the case and the plug before tightening the clamp bolts with the provided Hex key.  Tighten enough to stop the USB cable pulling out.
Note: The USB cable can go either way up (SRM logo up or down) it does not matter.

The Coiled USB cable must go direct to your PC - The kit is not compatible with consoles.. You will need to use a USB extension cable, our DIN cable option or have a USB hub near the wheelbase.

What wheelbase can I use?

The converted wheel can be used with any wheelbase / Direct Drive system. Because the kit plugs directly into your PC it is independent of the wheelbase.  Mounting requires a wheel base with a 70mm hole pattern.

The conversion kit has 6 x 5mm diameter holes on the 70mm pattern.  So you would either need to bolt a wheel side QR from your wheel base or make sure your wheel base has a 70mm profile plate to adapt to.

Disclaimers...

1. Conversion kits: Will only work on a PC consoles are not supported.

2. QR2 Base Side Option: Simon at SRM worked really hard to ensure fine tolerances on the QR2 Base side option and when tested here I get no play.  But some customers have reported minor play while others say they are absolutely fine.  Simon did his best with these and asks that you to accept that they "are as they are".  Please only order if you are prepared to accept that there might be a tiny bit of play.
