Worst reliability in its class (literally VW is 2 from the bottom in Consumer reports tests and reviews)Lets see:
GTI is 17” shorter than Integra
Corolla hatch is 14” shorter
Elantra N is 2” shorter
Kona N is 20” shorter
New WRX is 5” shorter
Mazda 3 Turbo hatch is 10” shorter.
So no, GR86 is not the only option.
SLOWEST car in its segment, 0 is known about the GR at this point
A literal SUV, no LSD
Cant find ANY confirmation on WRX length, but its universally ugly as shit with a park bench rear bumper, which you also seem to be worried about.
Again, Has no LSD which you said you "need"
So, all your list don't even exist yet or don't fit your own "requirements that canceled out the Integra.
Honestly all I've gotten from your posts is you're very picky, but for some reason require an LSD but some reason the weight of the car means nothing to you, so it must not be for track use. So... maybe snow? but then why not just get AWD? I also cant think of ANY reason you'd be so picky about length unless you are just poor at judging distances. Arguing 10-12 inches I'd understand, but your acting like 2 inches makes a car massive, which also implies you've never actually DRIVEN a proper family car, only compacts/sub compacts.
I have opinions too, but I justify and explain them, I don't just complain about how 2 inches somehow ruins a car, when you apparently just shortly a go upsized a car for an LSD, when you yourself name shorter cars... So it sounds like you made a bad decision, and now regret it.
Also feel free to look at now/then Sentra, accord, Altima, maxima, taurus, focus vs escort, old GTI vs new....everything has grown, name ANY car thats not grown.
Go buy a Fiesta ST, sounds like thats what you really want.
