Thanks. I'm just going to swap out my spur with the Spec-R version and use the white bushings.
After doing some fancy math, I figure a 106 tooth 64p Spur will allow me to use the same range of pinions that I use on my TC4 for both VTA and USGT.
What is amazing is that I dropped by my local track and ran for about an hour in prep for tonight's racing. In under 60 minutes I was faster than my TC4 and it was MUCH easier to drive. So much so that I brought it home and changed out a pinion, got it up to weight and will drive it tonight. Not a single spare part in 500 miles, but I'll give it a go...
