With those tires stretched and offset, did you have to do any fender work (Im guessing yes)? Thanks.

I lowered the coilovers until there was no tire gap. I do have fender work, rolled and shaved, and a bit flared.

thanks.

Yes, You will be good with those sizes and not have to worry about doing any fender work! You can even get by with 275 30 19 tires for rears, may camber a bit to prevent any rubbing.

E.g.,
19x10.5, 245/35/19 - a 285+/30/19 tire would fit this wheel much better
19x9.5, 225/35/19 - a 265+/30/19 tire would fit this wheel much better
It is the trend. There is no advantage or reason, just popular. I think it has a name... but I forget. But yeah, people want to stretch the skinniest tire they can fit on a wide rim so it kinda tucks under the wheel well flare yet the wheel itself kinda sticks out of the side of the car.

A more "square" setup or even a slight "bulge" is actually better for performance. Most people don't race their car, it is a show.
