With that et on your wheels you're going to want at least 5-8mm spacers in the back, they won't be flush with the Michelin's.. This is exactly what i'm fixing and i'm at et28

My last set-up was 275-30 and they looked good on the car, (front was acceptable, rear needs at least 5mm to match front) but what i'm trying to do is fill the fenders with a little more meat and trying to stay away from using spacers if I can, I'm also going to lower the car a bit more so hopefully it'll look the way I want with the 285-35 (not a huge difference from what i can tell)

I'm not a fan of stretch at all, kinda like the way those 295's look on your old set Very aggressive!
