Advice on alignment after lowered

I recently got my car lowered with ST v1 coilovers.
And while I was doing that, I replaced - strut bearings, lower control arms, strut tension bars. It's a long and welcome refresh after the stock ones retired. Plus strut pin removed.
Dropped front - 1.5". Rear - 1.25".

I went to alignment shop and got it aligned:
Front left camber = -1.3. Front right camber = 1.2.
Front left toe = .14. Front right = .14.

Rear left camber = -1.9. Rear right camber = -2.0.
Rear left toe = .14. Rear right toe = .17.

It rides great and cornering grip. However I wish for more turn-in response.
It's boring at the cornering as I turn steering wheel and it's rather slow to respond...not what I paid $$$ for. Actually it's less responsive than stock.
I'm DD so I don't need it darty and be unstable at high speeds.
But want to keep tires last long like before.

What do you guys think needs to adjust?

Btw I told the guy to bring down rear camber a bit. He say "there no more room". It doesn't sound right to not to me for the rear.

Bump! What'd be DD for toe settings? Leave the rear camber as is?

Lower your front toe. Zero front toe is a good balance between quick turn in and not super darty. If it does feel too darty at zero you can try lowering the front tire pressure 1-2 psi.

Ideally if your camber plates allow you would increase castor to fight the dartines and run zero toe to get easier turn in. Higher castor makes the steering want to stay on center but castor isn’t normally adjustable in these cars.

OK super thanks
And tire wear is not compromised?

If anything zero toe will increase tire life. The more toe deviates from neutral (0) the more tires wear.

Castor changes would not have any measurable affect on tire wear.

Tire pressure changes can affect tire wear but 1-2 psi would not make much difference.

Not necessarily; it all depends on how OP drives. Theoretically with 0* of static toe up front, dynamic toe will actually cause it to go negative (toe out). That would likely cause inside tire wear.

OP although it would be a good idea to play with toe, I'd also dial back camber in the rear (go more positive) and increase camber up front (go more negative). Find a set of street-friendly castor/camber plates so that you can easily dial the front end in to your liking.
