Who's making the move to STU?

Zewerr

I'm almost starting to think it actually may be related to my Z1 diff cover. I thought it did it with the stock cover, but talking to one of my friends who co-drove with me the first day it happened, I already had my new diff and cover installed. So, now I'm wondering if the air gap on the rear sensors is too big. It's hard to get a dial indicator in there to see exactly what it is, but my eyeballs estimate it's somewhere between 1-1.5 mm on both of them. I cannot find any specs for the air gap, but think it should be less than 1 mm. Is anyone able to check the gap on their rear sensor with a stock diff cover?
