I'll keep an eye on that. I haven't had any problems so far, even snapping a c-hub today. I didn't even notice it was busted for at least a full run.

Used Mi4CX with a dialed H30 setup? My finances should be in order after my next payday on the 15th. PM me when you've got a price in mind. I priced out the spool, diff, and axle parts from Schumi UK, but it was like $170, and at that point it it just didn't seem worth it.

I've only ever had the nasty traction roll issues with the old layout, before we stopped spraying. And even then, I was starting to get it under control. I didn't have issues at NORA, and I'm hoping our new carpet breaks in like that.

How often do you replace the spring washers in the diff? And how often do you replace the diff balls? I've been having some consistency issues with it. When I clean / reassemble it, it seems too stiff when I tighten it enough so that it doesn't slip, and it feels a bit chunky. I'm not sure if it's flat springs, worn rings, worn balls, the way I'm building it (too much grease?), picking up too much grit from the old carpet, or some combination. I'm still on the original balls, rings, and springs, and I haven't been sanding the rings at all. :/ I just got the new balls and springs I ordered, but for some reason I decided not to get new rings. I guess if it doesn't feel good, I'll know it's the rings, or me.

EDIT: I just double checked track width on my setup board... I'm at 190mm at the back of the rear wheels, and about 188mm front, so I can't space things much more.

What's the recommended technique for trimming axles? I need to knock the fronts down if I'm gonna keep using the narrow hexes. Should I just hit it with a cut off wheel, or go at it with a grinding bit of some sort?
