Complete list of all the customizations that can be "unselected"?

So here are some customizations that I know / I think can be unselected together with the option(s) that makes them unselected:

- Brakes: Super Brakes (Not sure what's the requirement for a car to have unselected brakes, can any car have unselected brakes?)

- Engine: EMS Level 5 / HSW Engine (Not sure what's the requirement, but I think it's the cars that can be HSW upgraded, but not yet HSW upgraded?)

- Transmission: HSW Transmission (Only HSW-upgradable cars?)

- Suspension: I saw somewhere that it is possible to lower the suspension of a vehicle further than the available options on LSC or HSW (Not sure about this)

- Turbo: HSW Turbo (Does this count? What's the requirement? HSW upgradable car, but not yet HSW upgraded?)

- Respray / Paint / Colors: Primary color, secondary color, trim color, wheel color, interior color, dashboard color: Any color with an index outside the first 170 paint index? (Not sure about the threshold there), so colors like Black Rainbow Prismatic (Index 220), Dark Holographic (Index 221) etc.
** Not sure how the interior and dashboard color work: Not all vehicles will have those as options, but based on my experiments, not all vehicles will apply the color on the dashboard (dashboard color will stay black / stock color)

- Headlights: Custom Xenon Light colors

- Livery: Special Liveries

- Plates: Well not really unselected, but unobtainable in a normal way: Yankton, Las Venturas, Liberty City, LS Car Meet, LS Pounders, LS Panic, Sprunk, eCola

- Wheels: Any wheels under the categories of Benny's Originals, Benny's Bespoke, Open Wheel (F1s), Street, Track (Includes Stance Andreas)

- Tire Smoke: Patriot Tire Smoke (can be set to be a crew smoke color)

- Window: Crystal Clear Window (Is that what it's called?), Green Tint Window

- Horn: Any complete list of unselected horns?

I am asking this because I already knew about the unselected color, wheels, liveries, and tire smoke beforehand, but I noticed that the crystal clear window is unselected, then decided to find out what other components can be unselected. And in the process of research, I found out about the others. I wonder if there's anything else that can be unselected that I missed.

And also how about bodyworks (e.g., Grille, Diffuser, Splitters, Spoiler, etc.), is there any unselected choice for them?

Thanks in advance, and please point out any mistakes I made

p.s. Sorry for the all over the place details, I cannot organize my mind
