Default Alignment Specs

Has anyone determined specific alignment specs, more precise and/or appropriate, than the factory ranges for our cars? Looking for daily/aggressive improvements on the factory specs that would also cut down on the inner front tire wear. In the past, I've relied on Lance (Lobuxracer) specs for both my ISF and my Supra but, not sure the specs carryover from the ISF to the RCF. I know we're somewhat limited to camber adjustments with no real options for the front but, I do have the adjustable arms for the rear. Input would be appreciated. I searched and didn't see a thread addressing this. Thanks all.

Lance - please chime in. I've PM'd you.

Am I missing anything?

Wes,
FYI there are FCA options.
I got the T demand ones. Figs has since come out with them too.
Guess you could adjust the camber more positive to get a neutral alignment if youre just looking for more tire life.
Car isn’t gonna corner well though..

Camber is rarely the culprit for inside or outside edge tire wear. It's almost always toe.

The first thing to do is ditch the OEM bushing at the back of the front lower control arm. It is way too flexible and makes the front toe out dramatically on braking. Once that is done, adjust for either zero toe or slight toe out. I run my IS at 0.04 degrees toe out on both sides in front. It turns in nicely, but does not offer ultimate tire life. I still have more inside edge wear than if I ran it closer to zero (BTW, I have Figs bushings in both spots on my LCAs), but I am happy with it the way it is.

Nothing else is easily adjustable without buying new components, and unless you're dragging frame, you shouldn't be having camber problems.
