Yes, 2 inch lift no rubbing locking it out both left and right. Havent tried it off road yet but i imagine with some articulation thrown into the mix might rub a little. But doesnt bother me its mostly on highway and light off road.

do you know what the reason of loss in mpg would be ? just curious

It looks like nobody replied to you. It's because of a heavier wheel/tire setup that takes more energy to get going. Also, the lift and tires poking out farther will have an effect on aerodynamics.

My dealership recommends this after market rim. It's direct fit:
RWC - SB395 - Black
SKU: RW839580B5144856.1-Subaru
Dimensions: 18x8 / 5x114.3
Center Bore: 56.1
Offset: 48

I'm in the process of installing them with the Continental Viking Contact 7.

Please verify the load rating before installing them.

Sorry for the bad news - I had to check...
I checked the load rating, and personally, I would not use them. Franco Caputo at Grand Prix Imports (RWC Wheels Canadian Import Seller) provided the following data:
  • LOAD RATING FOR WHEELS ARE 680-750 KG
    (caps are his)
The Ascent has a GAWR-R of 3,296 pounds (or 1,495 kg). With absolutely no safety margin (do NOT do that - load ratings are STATIC), for the highest load rated version of that rim (which may or may not be the 18" - probably not), that is 747.5 kg per wheel, with ZERO cargo shifting, and hitting ZERO potholes.

I've advised them of such - there are a few other listings I've gotten corrected.

For the Ascent, I suggest always going by the manufacturer load rating data, and not by a website's "compatibility" function - I've seen a number of rims (some load rated 500 pounds under per rim) mistakenly listed as suitable for the Ascent.

There is no point in specifying a limit for vehicle if you can't then drive it at that limit. It must allow for the normal expected range of dynamic loads, which means there is a safety margin. This is also true for the towing weight and tongue loads as well.

No, rims are static load rated. I don't know why. It doesn't make sense to me either, but they are.

Regardless, no one weighs their interior cargo and then ties it down so it doesn't shift left to right. And I've reached cargo limit multiple times in my travels.

Franco got back to me. He may have given me the wrong figures. He'll let me know tomorrow.

Obviously something isn't right. If a rim is static rated with no safety margin for 800kg, and you figure a vihicle is routinely going to see dynamic loads of 2x and maybe 3x static, then the only thing a 800kg wheel would be safe for is a golf cart.

The Subaru rims have a BIG safety margin. The Subaru selected tires also have a BIG safety margin (1,874 pounds and 2,039 pounds for 20" and 18" respectively), for a half- GAWR-R weight of 1,648 pounds.

That's a minimum of 225 pound margin, per wheel, which accounts for things like shifting tongue weight when towing a trailer that maxes the tongue weight down a hill (and thus shifting weight onto the axle).

Additionally, I just got the specs back from RWC. They are rated at 750kg (1,653 pounds). They used GVWR and divided in quarters. That did not take into account that since the Ascent is tow vehicle capable, that the highest axle weight must be used, which is GAWR-R at 3,296 pounds. (Half GAWR-R is 1,648).

Of course, even regular driving and loading up the car with no trailer (like my Virginia trip this summer) can easily load up the rear axle to max. We hit GVWR, and most of the weight was gear in the rear (we have a lot of cameras, drones and camping and off-roading supplies we brought).

So, the RWC wheels in question have a 3kg safety margin. That's 6.6 pounds, or, less than the weight of a gallon of milk. While I want a bigger safety margin, most people don't do with their Ascents the things I do with mine. ;)

Last comment on this. If you have 1000 lb static on each wheel and corner sharply, the load on the outer wheel can be 2000 lb on a smooth road. Hit a bump while doing that and it can be much more.

Safety factors for dynamic systems are usually 2x or more the max expected DYNAMIC load, not static load. If a component has a static max rating, you can be sure it allows very large safety factor over that.
