Default Wheel fitment issues

Having trouble figuring out a new wheel setup. Here are the specs:

Car: 15' IS350 F Sport
Front: 19x8.5 +35 235/35/19
Rear: 19x9.5 +35 265/30/19

Planning on using Hankook V12 tires and dropping on RSR Down springs

From comparing to OEM wheel specs, the rears will extend about 27mm further and I'm worried this will be an issue with rubbing on the fender unless I downsize and stretch the tire a bit.

For the fronts, with it only being about 11mm of poke, I was planning on adding a 5mm spacer as well.

Any feedback on this setup? Tips? Experience? TIA!

You’re going to have rubbing in the rear with those offsets and tire size. Im running 9.5 +40 with 265/30/19 hankook v12s and dropped on ark gts springs and I get rubbing on the back on dips and bumps. It will be even worse with +35 offset

Looks like i'll be going with 255/30 in the rear maybe.

Anybody else with a similar rear offset and lowered have any other suggestions?

I have my 255/30/19s on the rears. I'm on 19x9.5 +35 no rubbing or anything. However I do have camber arms in the rear and my camber is set to -3.0

I know somebody else on the forum is running 19x10 +38 with 255/30, RSR Down, and no rubbing.

19x9.5 +35 and the same tire would only push out 1mm more. I guess that might be JUST enough to rub in the rear?

255-30 is going to look pretty stretched on a 10” rim. My 265s look slightly stretched and I’ll probably go with 275s next time

It's going to look VERY stretched. I had 255s on my 9.5s before I switched to 265s and they had a noticeable stretch look which I hated. It basically had no sidewall because of the stretch.

I'm running 19 x 8.5 +35, 235/35 (Hankook V12 too).

Lowered on fsport shocks/springs, no rubs.

The 19x8.5 +35 in front isn't the issue, that definitely won't rub.

The concern is the 19x9.5 +35 in the rear that I'm worried about. People seem to report that more than a 20mm spacer in the rear results in rubbing, and with a 25-27mm poke on these in the rear, I am wondering about the fitment.

Nobody is running a rear setup like this? I believe Niche wheels are in this offset, anybody running a set of 19x9.5 in the rear of those?
