I'm going to look at getting a new spur & pinion in a few days. Looking at some PRS pinions down the road when they become available in the size I need.

I don't like the black grease in the transmission, as I feel it's too sticky. I'm running this car in 17.5 so I need that to be as free as possible. I use the clear diff grease and make sure everything has a very light coating.

Also, does anyone know where I can find a machined 72T spur for this car? I've looked at a few places online already, but it's either the correct size but not machined, or it's the correct size and machined, but not a slipper spur.
