If you machine your own plate, I believe the bore is 28mm but check to be sure. Also, if you are pressing studs, consider that the spacer needs to be absolutely flat on the faces and parallel to prevent wobbles AND the spacer must be counterbored to receive the heads of the wheel studs. Maybe you are considering threaded studs which require no counterbore, but will require some very aligned drilling and tapping. Not demanding this is how it must be done, rather sharing some concerns that may arise.
Apparently, I am fortunate that the drive cup on the balancer I own is small enough to work with no adapter. I was worried at first and was scoping out my adjustable adapter similar to the one shown with legs and studs, possibly setting it up for 3 hole wheels.
As I said, no doubt road force would be best if done correctly. However without going crazy I obtained balance and no shakes in the bars, with a proper dynamic balance (and added corrected the factory mistake of 1.0 oz of needed weights).
All the best with it.

Thanks,
I had not considered that the drive cup was different sizes on different machines. So as you suggested I will have to have a counterbore to drop the heads of the studs below the surface. That means starting out with a thicker slab of steel.
