Yes. I run a 0 offset for 44mm increase. Squirm is noticed at 45 mph and below, but turn in response is way up, almost as quick as my old slalom 124 Spider. Still the electric boosted steering has virtually no feel. KM

What is causing the squirm? I haven't had it happen in many years, that driver doesn't drive my truck anymore, but I had gotten ply separation that caused that. You can only hit so many road hazards until something has to give.

Not sure of the actual angles but assumed a stock with positive radius. I moved out past or to O scrub I think due to a bit of center direction stability. Not much just a feeling. It aligned near the center of stock specks, yet feels more eager to turn in either direction.
Probably an assumption on my part, and does not negatively impact the straight line stability. Other words it may pull very slightly either way on dead flat straight driving. KM

Ya know, mine was doing something similar, before I dug into the level. What it turned out to be, one or both of the universals on the steering column were binding up. I shot both of them with WD40, and that has taken care of it. Might try that yourself. I plan on shooting them with some Fluid Film sometime soon.

Thanks for the tip! I don't think it's that but will look. No bind at all just an eagerness to turn in in either direction, kinda enjoy that in this particular circumstance, not really noticed at 50 mph up. The toe is set as well as castor within factory spec. Squirt-O-lube will never hurt.

PS: Was kinda squirmy when I wrested in high school, now just too much of me to grab hold! KM

I think that's true of all us elders eh.

I wasn't too sure what you meant by "squirmy", but my 2018 EPAS was aimlessly drifting a lot. Dare I say, more so than with my 2017 EPAS. There's a TSB on this I think, for recalibrating the EPAS but it doesn't make much of a difference. Like, there's a "dead zone" plus or minus a few degrees to either side of centre where the steering wheel moves really, really loosely and freely. It's really obvious when I'm in low speed traffic, come to a stop, and the steering wheel will "slump" significantly to one side by itself. Also translates into a really weird driving feel. GM has converted to all-electric steering as well, but the steering on my Canyon was tight as hell, with none of the looseness with Ford EPAS. Tire sizes and alignment didn't seem to matter.

Squirm is when the tire center-line and steering pivot locate at the same point, rolling drag applies to both/either side. Feels like a loss of centering. My suspension tire combo is not that bad. No dead-zone and the feel is firm just not strongly centered as stock. As speed goes up the drag will cause slight shift to the amounts of toe and castor increasing center feel. Not a complaint just an observation on changes to my truck as it is now equiped. I enjoy the way it handles and consider it an improvement. Probably the result of my miss-spent youth finding fast lines around traffic cones! KM

So I bet your getting compliments... yes? When you get a change toss some front/ rear shots. As much as the rims are awesome, the rubber being a tad wider than 12.5 and tucked under the fenders looks amazing

Oh, yes I have, but I still haven't gotten it cleaned up. Hopefully the next couple days, and I'll be sure to post some.
I'm really liking it sitting this way.
