I can confirm what Sonofjim is saying. I have had the new Rim Drive for only 6 weeks - (ordered that way , not an upgrade) & even though it has soft black rubber feet, Mike at VPI said he is sending me another set - sounds like they're constantly modifying. He also confirmed a new rubber belt for the Rim drive will be available at the end of the Summer
VPI rim drive new feet
..just got them from VPI. These guys replace the feet on the motor assembly. The results are great... It now sounds even better than my makeshift soft footers. The smallest things make a real difference
