You haven't accomplished anything after bolting on these parts.
You don't have your ride height set with you car on the ground, so you can't have camber, caster and toe set...
With 1.14" torsion bars you won't experience 5" of suspension travel like you show.
I can only tell you that a 18x9 with +30 OS should fit a 275/35/18 tire on the front. With your Dodge D100 rotors and first gen Viper Brembo 4 piston calipers you will need a rim that clears those.
You don't need to get a 9-1/2" wide rim to mount that tire. Unless you like to have curb rash on your rim lips?
Who's 17x4.5 Race Star 92's are you using in the pics?
And it looks like you waited to have the car painted to find rims & tires that just fit? That's backasswards.
Nope, not true. Almost none of it is right.
The car doesn’t have to be sitting on the ground. That’s the beauty of a torsion bar system. If he sets the spindles at right height and sets the alignment, it will be exactly the same sitting on the ground. He just has to set the torsion bar adjusters to achieve that height. And really, as long as it’s close the alignment will be close too.
The suspension travel range is set by the bump stops, not the torsion bars. He might have 5” of travel. Depending on the ride height he sets, he might not ever see full compression. But his ride height looks pretty low, so, he might. I hit the bump stops on my car with 1.12” torsion bars, so it sees full compression. And bump stop to bump stop is a little less than 5”. I don’t see full extension though except on a jack, my ride height isn’t quite centered between the stops.
And those aren’t the brakes he’s running.

If I set my car on jack stands, account for a small rake, measure where I want my spindles in relation to my fenders... I can't replicate ride height without my car being on the ground?

I never said I had 5" of travel nor did I imply it. That is your figure and I previously corrected your statement.

I'm running Mercedes 13" front rotors not d100 rotors. And 18x9 +30 SHOULD fit based on what, your assumptions?

Nope but in the custom wheel world, readily available hoop sizes are 8, 9.5 and 11. Yes I can get 9" and 12 or whatever size I want but the others are way more common. 275/35-18 is rated for a 9to10" width so I don't understand the weird passive aggressive curb rash statement?
Who's 17x4.5 Race Star 92's are you using in the pics?
It's just one a buddy lent me. It's a 26" tall tire with a hub to outer wheel distance of 3.75. I wanted to see how that compared to some of my other measurements.
And it looks like you waited to have the car painted to find rims & tires that just fit? That's backasswards.
What could I have done differently to avoid doing it backasswards?
BUT...

Yeah he’s wrong. You can totally set the alignment like that. You just have to duplicate the spindle location when you set the ride height.
That brake set up adds about 5/16”. So you’ll need an extra 5/16” of backspace, or 5mm of offset. Same as my car. Which is what he’s quoting for the specs,
my wheels. I run 18x9’s with a +35mm offset, drdiffs 13” cobra style brakes (same hub as yours), and a 3mm spacer.
The 18x9.5’s should be ok. The difference in the section width of the tire will be pretty small compared to an 18x9”. The tie rod shouldn’t be an issue.
Shouldn’t. Tomswheels had multiple sets of 18x10’s for the front of his car. Now, a bunch of that was on the outside to his pulled fenders, but not all of it was.
You should be able to run 18x9.5’s. The beauty of using offset is that you should be able to use a +35mm offset, same as mine. It’ll put the centerline of the rim in the same place as mine. The section width will cheat out a little on both sides compared to my car. It will be tight, as you’ve found.
And as autoxcuda pointed out, you probably won’t hit full steering lock and full suspension compression at the same time. To be honest, I don’t know that my set up would pass that test. I just know they don’t rub.
You can do lots of math and fitting, but when you really push the limits you just have to see if they work sometimes. Are your fenders rolled yet?
