This. 1000 times this.
Rigid frames are the death of holonomic systems like this (omni or mecanum drive, swerve is a whole different ball game I don't have enough experience with to talk about).
You want flex because you want each wheel on the ground at all times. Not doing this will result in unpredictable behavior... well, ok, it's completely predictable given that you know that you're driving over uneven terrain and what the normal force on the wheels is and... blah blah blah.
