Agreed. Seems like the Camber could be improved (based on the initial test w/the framing square). Seems the Toe settings are a likely suspect as well.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Thanks. It's going in the shop for a full front end alignment in a couple days.

If you get a decent tech that understands alignments, you should be able to request NEG .5 - 1° Camber w/as much Caster as he can dial in while targeting that slightly negative Camber setting.

Factory spec would be somewhere around zero - POS 1° Camber & not tear up the tires aggressively so the negative values would be similar but allow better tire contact patch when navigating turns @ speed. My lowered 1-ton CC dually drives like a sport-truck on curves w/similar settings (on LT + load rated tires to boot).

Decent enough numbers to work for sure. Even though you're happy w/ the work, there's def room to make it even better.

My dually was/is NEG .6 Camber & 6.9/7.4 Caster @ aligned ride height. Crazy how it transformed the driving experience even w/ the skinny 16x6 OE dually wheel/tire set-up.

Re: Front Tire Wearing On Outside

I hear ya man. As far as my 49 it has a 92 S10 front clip matted to the stock frame that has been boxed, Camero Big 10 Rearend so trying to get all this aligned right is a bit of a chore. A hell of a lot better than it was. Getting Michelin pilot Sport 235/45 r18 put on this Friday.

Gotcha. Just promoting the idea that even basic stuff (like your S10 based chassis & my dually) can really be woken-up w/some good settings.

The tire sizes you chose are better (more aggressive) vs what an S10 would have come with so that's yet another plus.
