I’m currently 285/35/19 - 305/35/19That 315/35 is a touch tall, I'm assuming with the 285 front, the wheels are going to be 20x10 ET35 (front) and 20x11 ET50 (rear), which is what I'm running on my '19. I had the same wheels/tires on my '16 and it had a BMR SP080 spring setup, and I would very occasionally bottom out on a something bridge, and get some minor contact.
The 315 is also a touch big, why not just to a better matched front-to-rear sidewall height, wheel width fitment, etc., and go with a 305/35[?]
This is a terrific site to check fitments, get a good pre-viz, etc.:

What width rims?Front offset will be 35mm and rear offset will be 50mm
I’m an idiot. The front is 35mm offset. I won’t rub then with 35mm in the front with a 285 tire, right?If your front is 30 with 285 you will rub. As for the rear you should be good with . 50. I’m on Ford Performance springs drops it 1 inch... not sure if the eibach pro kit drops it slightly more
Et for the front will be around 34 or 35 if I’m not mistaken. With 34 front 285 I don’t rub
