I used loctite brand... It's just a matter of the shaft not having any bite on the scew so it slipped off. Usually something pops loose on the shakedown run, hence the name
I received my FTW body today, took a brief look at it, but haven't cut and sized it yet. Will probably get that done the next couple days with my standard scheme... which I might add goes well with the lines of the FTW body.
So things I'm going to test Sunday:
Reduced rear toe
Shorten Rear Camber links on the hub side
Run shorter rear arm, inner on hub
Set proper camber/ ride height/ droop
Play with brakes some more

Obviously not all these at once
I think some off brand fiber discs with metal pads would give less bite... might have to look and see what I have laying around that'll fit. Also lightens the drivetrain up a bit...
