I was wondering if he was actually running stock wheels if he was stretching the rubber that much on the back. If it is indeed stock wheels I'd probably agree and but also I'd go with 12 front and 15 rear (what I've got on mine) instead since he's also stretching the fronts.12mm front and 15mm rear is a good option but with 305/35 tires you might need to go little smaller in the rear like 12mm.

Same here!13mm up front
15mm in the rear
These are the most common sizes for our cars, I went with these sizes also and I think they are perfect for a non poke flush fitment. I went with Burger Motorsports spacer.
With those tire sizes don't get spacers.Which spacers should I get if I want to keep my stock wheels and lower the car with H&R lowering springs?
Tires I want to get
Front 275/35/19
Rear 305/35/19
I want something flush that won't rub,
In your opinion, what do you think would be the best spacer size with the widest tire?With those tire sizes, don't get spacers.
I have 285r (15mm spacers) and 265 fr (13 mm Spacers) and I rub very very slightly on hard corners with bumps. Otherwise stance is perfect. With spacers adn an additions 20mm rear, you're definitely going to rub. I'm on H&R springs btw.
