Push the wheels out with 20mm spacers front & Rear and put on the rear SPC camber kit, I think it makes a huge difference, then you can decide if you want to take out the Eibachs. When I put the rear camber back closer to stock, it actually raised the car about 5mm. You can always go with some adjustable BC coilovers (about $995) sell your Eibachs, then you can adjust the ride height where you want it.
I don't think it looks too low, but definitely need the spacers. I'm running 15mm front and 20mm rear, but my Nismo rims have a more aggressive offset, I would definitely go 20mm on front with stock sport rims.
