Everyone I’ve ever seen using a Simucube base has been using iRacing. I’m pretty sure it’ll work well.
My wheelbase (Accuforce V2) is also not on that page and it works fine.
iRacing’s wheel and pedal compatibility is pretty complete. It’s games like Dirt Rally or Forza Horizon where you see the occasional issue, not iRacing.
So here’s the thing. No company selling you a wheelbase (especially a DD wheelbase) will promise you it won’t hurt you. There are disclaimers all over the legal info for these products saying to keep them away from children, etc.
These things are massive, power hungry, industrial strength motors. There are dozens of ways they can hurt you. iRacing and other sims have options to reduce the forces in crashes and when parked. The software that came with my wheelbase also has options like these.
But, there are driver errors, USB glitches, etc.
If you’re looking for someone on the internet to promise you it’s safe and that it won’t hurt you when using it with iRacing, I don’t think you’re going to find that assurance.
