I kept tightening it down. I have about 4-5mm of thread showing right now. I heard a sound from the car, didnt really sound like a slipper squeel. I thought maybe the tires were slipping as they were running the track pretty damp (CH). Either way my pads are pretty shiny. The triads are out of stock and there is no eta. They said they are out of the pads to make the kits. I might pick up new pads and try the vts again. same crappy pad, but more surface area. We thinking garodiscs, but I am reading that people are tightening them all the way down and backing off 1 turn. Sounds like those pads are pretty slick and I am unsure of how tunable they are.
