18x9 ET30 with Hankook V12 245/35
18x10 ET25 with Hankook V12 275/35

Two things I’d like to verify if possible, though:
1) are camber plates necessary for a proper alignment on stock suspension?
2) will lowering on H&R springs potentially change the answer to #1?

Thanks in advance.
Thank you for the kind words Primm, and congrats on the new (to you) coupe!

The 18x9 ET30 and 18x10 ET25 setup is a very popular one, and will fit without much drama in the following configuration:

Front: 18x9" ET30 with 235/40-18 tires
Rear: 18x10" ET25 with 275/35-18 tires
  • Front negative camber may be required.
  • Popular fitment.
  • 245/35-18 front tires may also be used with moderate negative camber.

In regards to your questions:

We would recommend opting for a camber plate if you intend on lowering the car at all over stock. At stock height, there will be moderate camber required (less than -1.8˚).

If you intend on fitting those H&R springs then you would need to run around -1.8˚ to -2˚ in front depending on how low you end up.

I hope this was helpful information, post up some pics of your car when you take delivery as well. I'm excited for you!
