VPI Rim Drive vibrations

I've only just come to this exchange - so you may all have gone away by now...
I've read it all because it addresses many of the problems I've had with rim drive - and I'll try the suggestions, particularly Stringreen, Thanks.
One thing I don't understand. Various people have put various things under the motor assembly. It isn't clear if they bypass the stock feet and rest them on the underside of the motor casing or not. I can only raise the motor assembly a very tiny amount before the rim drive is so high it prevents my using the ring clamp.
What am I not understanding ?

Hello...... Anyone still there......

Could this problem occur with a VPI Traveler on a rigid wall rack and shelf?

TIA!

The VPI Traveler table is a belt drive table. The issue being discussed here converns VPI's rim drive.

2014 Oct update - Thank you everyone in this thread helping me to resolve the HRX vibration issue caused by the Rim motor drive pushing against the 30 lbs HRX Super platter. As my components improved, the noise from the vibration became extremely intrusive to the music on the LPs. I contacted Dan at Eden Sound with his TerrCone footers on both the Rim Motor drive and the HRX turntable footers. And it works getting rid of the vibration! Unbelievable!

The improvement in the sound is quite spectacular; the clarity is pure like electrostatic speakers. There is no smearing in any frequency of the sound. My suffering over the years from the wobbly footers on the HRX and the motor rim drive is over. The rumbling of the rim drive that impacted the groove of my LPs are eliminated, and I have no idea the music is so much richer and fuller. The highs are skywards and the lows are reaching the subterranean deep. The mid bass is agile with speed; and surrounded with bloom of air. All these gain from the Eden Sound TerraCones is astounding.

No doubt the noise level has dropped tremendously from the chatter caused by the vibration from the rim drive pushing the heavy HRX Supper platter. All the energy has transferred from the shaking motor rim drive using the cheap rubber flimsy footers on the original motor drive. I have no idea how poor the HRX footers are until I replaced them with the new Eden Sound TerraCones. I am amazed when I turn on the motor drive now; I got no vibration from the new TerraCones. Even at 45-rpm. In the old days the 45-rpm spinning is such a pulsating rumba dance. I touch the motor drive with my fingers now with the TerraCones, and hardly any sensation. I actually jump for joy when I first touch the motor unit running as I felt almost nothing; Wow!

Now I find the details from the LPs uncovering in the open. Live nightclub and live concerts events are wonderment. The inner voices from audience as apart of the event is ear catching lifelike; you can count every finger touching each string of the instrument like the guitar. It's a transformation of a new record collection from my listening sessions. I wish I had got word of Eden Sound for my HRX Rim Drive sooner.

Anyway, thanks for the solution everyone pointing me towards Eden Sound.

Mmerlionus, I found the Classic platter to be a big improvement over the Super Platter on my Super Scoutmaster Ref. with rim-drive, not only in sound but also in how more smoothly running the rim drive works.
