Re: front/rear diameter differential
To maintain the factory front to rear tire diameter differential of apprx. 1" from front to rear I'd go w/ a 255/35/18 PS2. The problem is visually you will be increasing the fendor gap front & rear by 1/2". Which you may live with or could be offset by lowering the car w/ stock adjusters to get where you like the look, but this tire combo effectively reduces ground clearance roughly a 1/2". I assume you know the 305/30/19 gives up just shy of an 1" in diameter to the stock 285s. So any additional lowerering, mainly for front spoiler, may create road, driveway, speedbump, etc. issues. Personally, I went 255/40/18s & 295/35/19 which both are slightly taller & lowered max front & rear w/ cutting 1/2 the bushing which gives it a very low slung look, but really is not too low for regular driving. At least mt opinion, as I haven't siffered any ill effect or clearance issue as I am aware it's low & avoid damage by driving accordingly over speed bumpss, up driveways, etc. On the street rarely an issue. Take a look in my garage & you see pics to get a good idea of ride height & overall look of lowering.

I just bought 265/35/18s for the front and already had 305/30/19s in the back (was running stock size up front before).
Both are now hankook Ventus V12 where before I was running Khumos Ecstas in front and V12s in back.

I see most folks round here run a 265/35 or a 275/35 with a 305/30 rear. It usually depends on which size front the tire manufacture offers; depending on manufacture, they usually offer one or the other. Both seam to be OK & don't set off any active handling warnings.
Lots a threads on tires if you search.
I'm also due for new shoes & I'm going w/ 265 & 305
