I discussed this very thing with a chap here once, and we came up with the following:

Rear 19 x 10.5 +45 with 285/30/19

It would take a slight increase in negative camber, front and rear to make it work, but we think it would work.

But I think those are about the limits. Does that seem about right @Sasnuke ?
That would work and a couple people do have that same rear fitment. But literally everything has to line up perfect...no margin for error at all. Even the tire brand would need to be looked at carefully for tread width.

Did we have the front limits about right as well? Or are we off there?

The fronts would be fine too.
But like all things with rims and tires, vehicle height and rim design need to be factored in.

You can't slam it on Superdowns on a 245 and expect it not to hit something. Also to clear the caliper, +35 is not a guarantee if the rim spokes don't curve outwards enough from the center on the initial distance.

Agree on all points, wheel design, and specific offset in relation to it, and specific tire make/model make a difference when you're down to the millimeter.

Hi Guys,

Trying to buy some Volk SF-Winnings for my '15 F Sport 350. I'm lowered on RSR downs.

They are:
Front: 19''x 8.5" +38 offset with 255/40/19 tires
Rear: 19"x9.5" +29 offset with 275/40/19

Will these fit or will there be any issues?

Thanks!

For the front, the most I would push offset for an 8.5" wide wheel would be +30-32
As for the rear, I think +38 on a 9.5" wide is as far as you can go without rubbing.

Those numbers are assuming you're running a tire setup that is about square with the lip, or even slightly stretched to clear the fenders.

For example:
Front: 19x8.5 +32 245/35
Rear: 19x9.5 +38 265/30

This will also depend on tire brand. YMMV.

I can attest to this, I went +35 on 18x8 in front and still needed 3mm spacers to clear the calipers.

I probably should have checked on here earlier before ordering... But I just ordered SSR GTX01's 18x9.5 +40 square setup. I'm lowered on Swift Sport springs, will I have any trouble running these? Would spacers help? What tire specs do you guys recommend?

The rear will be fine...you can use a 255/35/18 for a slight stretch, or a 265/35/18.
The front will likely hit the steering knuckle. Since you're running a square setup, you'll need the same size tire on the front.
You'll need a spacer for the front...but until you get the wheels to test fit, you won't know how big. I would guess a 10mm spacer at least.
Of course it might look funny with the front wheels poking out.
Really a 9 inch for the front is the biggest you wanna go.

How did you fit 20" rims ? I thought 19 was max? Looking at 19x10 on the rear for my IS. Any problems going that wide?

You can fit 20's...although the tire is pretty much a rubberband at that point. I would stick with 19's.
