Right. But he was asking about doing it himself.
As far as I'm concerned, I am my own "good" shop. I did my alignment when I refreshed my suspension and lowered it. Was aiming to just get it close enough to be fine for the drive to a shop. But I spent an extra few minutes since I already had it all set up and got it pretty darned spot-on. I erred my caster to be a bit strong to the positive because I didn't have an easy way to measure it and positive is much safer than "zero" or negative. Anyway, that was three years (to the day!) and about 25K miles ago and my tires have always worn very evenly. I scrutinize the treads at every 5K-mile rotation, just daring something to be off.
If you turn the wheels from straight you can get a rough idea of the castor angle using the gauge I posted. So if you are on the drivers side wheel you get the camber measurement at straight then turn the wheel left and check that reading then do the math.

If I had planned on staying with my home-grown alignment, I would've invested in one of those gauges. Still, it requiring math prompts me to leave it as-is. You know we get more dumber the further south we is.
Yes! It looks a little taller when you are driving it, although i measured them side by side and they looked identical
The ride is very different though, you can now see and feel front moving seamlessly over bumps, while previously it was hard as a rock

Sez the guy with the self-calculated Helmholtz chamber for his exhaust drone.
Selective nerding, my friend.
And, actually, I only lead others to do those. Mine doesn't drone so, somewhat disappointingly, I never got to play with the science on my own vehicle.

Is there one on the intake also?Sez the guy with the self-calculated Helmholtz chamber for his exhaust drone.

I believe that's a factory chamber.

IIRC, there's two in the intake duct. A bulbous one underneath and a long one that extends alongside the intake manifold through a square opening in the beauty cover. This is why the smooth tubes cause the intake growl sound.
