I've updated the sheet with Compare Front and Rear links for each row that you can click on to open it in wheel-size.com, if someone has a chance to measure the stock fender clearance (from tire sidewall to inside fender) and wheel well clearance (tire tread to fender), please let me know, otherwise perhaps I'll try to do that this weekend, then we can calculate for poke!
This is awesome stuff! I will let you know once i get my nitto nt-5 - 245 35 fronts and 285 30 rears on my tsw sebrings 19" 8.5 30 and 9.5 40 setup - AWD lowered on Eibach springs
1) I added the Federation Stinger specific set up to the list (275 rear instead of 285, +40 offset in the front instead of +30)
2) Here are the wheelwell and fender clearances on stock 19's, these measurements are from the most protruding parts of the tires. This is from the sidewall (the rim protector in this case, not the edge of the tread) to the INSIDE of the fender (only about 1mm or so), and from the top of the tread (tire is pretty new, not much tread wear) to the fender.
GT AWD with Eibach Springs (going direct from Eibach here and not real measurements)
Front drop 1.4” = 35.56 millimeters (36mm) new clearance clearance = 8mm
Rear drop 1.2” = 30.48 millimeters (30mm) new clearance = 14mm
Added the above clearances to the Reference tab and updated the links to wheel-size.com to pull those references for both Stock and Eibach springs. It would be great if someone who has eibach springs on stock 19's to get actual measurements of fender and wheel well clearances

For what it's worth, I used a standard 6" woodworking square and for convenience used my phone as a level to measure from the face of the sidewall (which happened to touch the rim protector in this case) to the fender. For measuring the tread to the fender, I used a separate straight edge to extend the tread to the square. I can take pics of what I did if that didn't make sense

It's tricky. I have an inside/outside caliper with digital readout, but getting it wiggled in to measure isn't always doable. Some degree of eyeballing may take place.
I'm sure 20x9+30 will be fine, no rubbing, it's about 1/4" in and out from the common 8.5+30.
255 I think is the maximum you can run up front however. Check out the spreadsheet above, you can click "compare" links on stock wheels and plug in your values on the right to see the differences.
Alright, I added you to the spreadsheet. It looks awfully close with Eibach suspension, keep in mind that I don't think this is perfectly accurate, I think there's actually a little more space than what's depicted at wheel-size.com.
Oh, I see you had 255/35r20 tires listed, but at 20" size you'd want to go with a 255/30 instead, which gives you clearance, and diameter is then perfect.

A 255/35 however is going to be too tall. 255/35 is stock for a 19x8.5 rear tire, but once you go up to 20" wheels, a 255/35 will probably too tall, especially in the front where you have a little less clearance. You could probably make it fit, but be aware that if you lower your car, you might be pretty close to it (unless you're going for that tucked look). 255/30r20 will be bang-on stock diameter, 255/35r20 will be an inch taller than stock.
If we go straight from the numbers, front stock wheelwell clearance is 1.75", Eibach drops 1.4" to give you 3/8" remaining, add a tire 1" taller on that and you'll be pretty tight. +30 offset will get you pretty flush, +35 offset would be even a little better.
Just as a reminder, here are the stock/eibach links, the 255/35's on eibachs are showing potential contact (red fenders):
It'll probably work pretty well, but you're on the edge of what the standard recommendations are, but you can certainly go beyond that if you're brave!
