You make that sound like a negative. I don't see any issue. in fact think it a good thing - some of my hoons make me feel like I'm on the 'ring
Impreza's (and so many other cars, and new suspension ) are 'ring tuned, as well as in many other situations too, including the plain old road

not suitable for both imo as much as kw. Kw will do both and compliance on road will be better. Just depends how much money (as whiteline are not cheap) and where most your focus is for track or road

OEM GD STI front 217lb/in (at ride height) - 223lb/in (before coil bind).
Unlike the wr99 Bilsteins on your type r, stiff compression damping allowing soft bump stops - maximising the available bump travel - combined with P1 springs front 194lb/in.

They didn't consider at what speed flat ride occurs. They didn't consider front and rear ride frequencies. And why would they, it's not compliant enough too be considered a road suspension - the v3 GD wrx front spring rate 340lb/in, the v3 GD sti front 455lb/in (515lb/in GD V3 clubsports). They're not concerned whether the lowest height setting delivers less than optimal handling, on an Impreza. They've just got to be stiff enough not bottom out, at their lowest ride height setting .

Much stiffer sway bars and over lowering are also common ways I see people ruining the handling of their cars, centre of gravity and axle compliance are really important on newages.

I find shocks/springs with a custom geo setup can be good for both withought massive compromise on track but I know plenty of people that run coilover setups for daily drivers that rate them.

Have a look what the guys over on iWSTi think - the consensus is overwhelmingly positive, 'better than OE shocks & springs'

If it were a daily drive then I'd certainly look into spring combo, but if toy then you want something that's top on both sinarios, and lets face it, when we go on a car cruise etc like snakes pass etc the roads are pretty smooth and very windy and I'd definitely want good suspension for them roads.
i wouldn't be put off by snet's mr avoid anything coilover.
as said kw V3 are very bmw'ish like drive which actually made me smile

Yes can't agree with this enough. I've had coilovers on both my Imprezas when I've bought them and found them awful on anything other than mirror smooth roads which is a rarity in this country. I'm currently on prodrive Bilsteins from the rb320 and couldn't be happier. Little bit stiffer than stock STI but with the proper rebound and compression giving the compliance needed for three bumps and undulations on b roads. I doubt there's a better set up out there as they are designed for our roads. I can hit the local terrible b roads like a rally stage and go 10mph faster at least compared to crashy coils.

Thing is, a lot of what is fitted is budget stuff like BC's Tein's etc. You need to raise the budget to get decent performers, and they are out there

That ride was so bad, that when I broke a road spring I had my local dealer switch the lot to stock all round.
In fact I have an Autocar Newage buyer's guide that specifically states not to bother with the Prodrive suspension upgrade.
I've just come off of 3 weeks of daily driving and never during that time, nor in the 20,000 miles I've done on the V3s, have I entertained any thought of going back to stock.
The thing I like the best about the V3s is that I can adjust them according to need.

The oem set-up is a strut, The kw v3, on a gc/gd Impreza, are also struts. A smaller diameter coil spring, than oem, with an adjustable lower perch and adjustable damping, but they are both struts.
I'll say it again, if they didn't accommodate such low ride heights, the springs wouldn't need to be so stiff, for a road car.

Flat ride is a road car calculation. It's not necessary for the v3 to take it into account. If they did, on the kw version 3 sti strut, they'd probably end up with a 450lb/in rear spring, with a rear ride frequency of 2.5Hz (tarmac rally car frequency).

All the theory in the chassis internet world is fine but real world experience counts too
Best I ran was a set of Eibach Superstreet's on a 370bhp blob for 2 years and they were superb. I hooned them all over the best (and certainly not so good) UK roads, and on track.
They performed very close to OE dampers and springs, being just a little more firm at slower speeds, but wonderfully compliant at higher ones, with plenty of travel, never crashing, no bounce
(Hope you haven't totally given up OP)

What's the best coilover you've ran 2pot?

Whiteline group 4 280/224lb/in. A bit stiff at the front for me.
Even Whiteline group 4 race had flat ride, around 100 mph, 504/448lb/in
BC do a low spring rate strut (longer travel to allow for the lower spring rates) 224/168lb/in
Your P1 springs are 194/157lb/in.... they ok?
