Props on coming up with a design that fits the spec v's for the strut bar. I for one am no scientist, but I don't think you can feel a difference in the car. I would probably place it under the placebo effect. I didn't feel a difference installing my intake, it just made more noise. I didn't feel a difference installing my exhaust. Just made more noise. The header was a little bit different. I could notice the powerband shift higher and have a little more fervor up top.
Strut bar? Not so much I suppose. I think you just wanna justify what you did and from a psycological standpoint my point is 100% valid. Almost all aftermarket strut bars are useless without being combined with numerous other suspension mods.
Out of all my mods, by far switching to more aggressive tires has been the single most noticeable change. Nothing else comes close. Intepret that as you may.
I have 35% all around, it's great during the daytime, but it sucks at night and my tint is incredibly light compared to most modified cars. If you think 20% was manageable more power to you but I can hardly see through my stuff at night.
Also the spray you mention, VHT nightshade I presume, is up to you how dark you want to go. However, if you're saying you want to be blacked out use the window tint example to compare. Can you see s*** out your windows at night with 5% tint? How about 15%? How about 35%? How about 50%?. The point I'm trying to display is that it's going to 100% comparable to your visibility, except imagine that light is trying to pass through that. Even HID's won't cure that problem. If you keep it lightly tinted you might be ok, but if you want the blacked out look, paint your inner housings a gloss black, I think that will give you the look you're after.
Also, before you purchase HID's think of this: If it's too good to be true then it probably is. Cheap HID's are exactly that, cheap. They are terrible at producing output, color doesn't equal brightness infact it's a negatively correlated attribute. The reason OEM HID's are expensive is because they are quality. Car enthusiasts don't need the rap of blinding people with bright lights in addition to having loud cars and so on. If you want to pursue that route, spend your money right once and get a projector retrofit. TSX projector produces absolutely stunning light and is a great price alternative to a lot of the more expensive ones.

Our throttlebody is no where NEAR 4". I mean not even close. We have a 60xmm(unsure of exact 68mm IIRC) TB and you're using a 4" intake path which is over 100mm. You running into a HUGE bottleneck and it isn't going to help you at all. Like I said the turbulence near the MAF could actually rob you of performance.
Please don't let my cynicism get you down and don't mistake it as anything but helpful insight. I admire the effort you're putting into your car I just wouldn't want to waste my money if someone knew something I didn't, especially from personal experience.
