Question to anyone who has a GT Omega ART cockpit with a DD wheel

[Ascendancy]

So I just bought the GT Omega ART rig and I'm going to pair it with a Fanatec CSL DD wheel but I'm kinda worried about the rig flexing with a DD wheel attached to it can anyone let me know how bad I can expect the flexing to be? (My wheel is 5NM btw)
