The rubber feet (the original feet, I removed the newer and taller upgraded rubber feet) are not making any contact with the Ultra shelf-they are suspended a few millimeters by the Point Pods and extra plate. The feet just happen to just make contact with the edges of the Point Pods to help secure the pods within the motor assembly. Just turned out that way with the stock size Point Pods.
Improved my VPI Super Scoutmaster w/Rim drive
I recently installed Symposium Acoustics Point Pods, 1 in front, and 1 in the rear of the motor assembly. The Point Pods fit exactly in between the rubber feet, so the rubber feet hold the Pods in place but are raised above and no longer touch the support shelf (Ultra shelf). I had to raise the height slightly to allow the rimdrive to meet the center of the metal rim of the Super Platter. Symposium made me 2 additional thin plates each measuring 3.8mm which I placed 1 on top of each Point Pod. The sound is more rock solid, and I no longer get a very slight vibration coming from the motor assembly due to the rubber feet. PRAT are all improved. I have the 10.5i tonearm with a Lyra Titan-i cartridge. Highly recommended!!
