Ugh. Can’t believe I’m saying this. But I have to agree with you. Stretching is ghey.
I also run the EXACT same setup. 17x9 +17 255/40/17 all around.
However, My fronts need no pull. My rears need a little roll.
I’m running JIC FLT-A2’s at about 3’’ drop. With OEM spec alignment.
I personally don’t think people should be running things like 215 on a 17x9. It’s just plain dumb in my opinion.
I also find that the 255/40/17 on a 17x9 kinda looks a little too meaty. I prefer the way a 245/40/17 looks. But, I like my grip.
