Sorry should have been a bit clearer. You can research and design yourself then but the profiles direct from the manufacture, as some else said they will cut them to size for you for pretty cheap.
However many people (like myself) just buy a kit from a company that you know will work and often comes with well made pedal plates and wheel mounts. I got mine from here https://sim-lab.eu/
Good thing about getting a profile rig, is even though I got mine from sim lab as it's standard parts I can just buy additional upgrades for it myself.
Cheers, Mike. I'll check these out. Looking forward to getting al this set up and then actually being slower than I am with it mounted to my desk
I only have the 8nm CSL DD, so these will be sufficient to hold it nice and steady I'm guessing?
