Problems with suspension setup
My issue: Car seems to "wander" or "pull" towards dips in the road after coilover install, and gets worse at high speeds. I know some of this is normal but it seems very exaggerated after coilover install. ALSO, the steering wheel will not return fully to center without driver input, as in I have to center the wheel myself (possible result of Whiteline ALK?). One final thing, I have a good vibration in the rear on hard acceleration, but I believe this has to do with lowering the car.
My setup: Ohlins R&T with Swift 10k/9k springs.
8 clicks out from hardest setting
Whiteline RCK and ALK (maximum caster set)
Alignment specs: FRONT = -2.3 degrees camber
0 degrees toe
REAR = -1.7 degrees camber
0.24 degrees toe in total
Everything was installed and alignment performed all in one shot. Everything is tight and torqued to specification. Other than these issues the car corners and handles well.

Tramlining. It's usually caused by toe-out but can also be caused by tire wear. Did you get new tires with the suspension or are you running something half worn from your old suspension settings with the new setup?
The other issue that comes to mind since you mentioned the steering wheel isn't returning is that the car is too low and there's binding. How low is the car now? Did you install a roll center / bump steer kit after you lowered it? With what you have invested in those Ohlins, it's going to be something you want to do.

The not returning to 100% center without input is the drag from the spherical bearing top mount, that's typical/normal. 0 front toe will cause some wandering.
Are the factory front camber bolts in the same position on each side? If they're opposite, and the alignment shop just used the camber plate to make up for it, it can cause some weird handling characteristics.
How much is the rear lowered? The EvoX's can max out the CV joints if lowered too much and cause vibration.
