I'm looking at either a set of Enkei GTC01's or Koya SF03 or Koya SF05. Size I want is 18x8 but the standard offset for 18x8 is listed [here] as ET52. (std size 18x7.5 has an offset of ET55)

However all of the aftermarket (AFM) wheels listed for the levorg are a slightly different offset and I don't know if a slight variance matters. I spoke to a sales guy at Jax tyres and he stated that the rims they have on the web site that he showed me are guaranteed to fit, even with their different offset. ie the Enkei GTC01 in 18x8 has an offset of ET40, which he said will be fine. Their web site also gives you the option of an ET of 45. [Jax Tyres Subaru Levorg wheels]

So... I want to ask those of you that have aftermarket wheels fitted, what size and offset did you end up with and do they rub at all? (thanks for your input in advance)

Scott you have asked the same question that I want to ask, my rims I am looking at are 18*8 offset of 35

Oh be careful with an offset that much as the standard for
8inch wise as far as I know is +52.
At least see a tyre retailer and find one that will guarantee a wheel of the same size will fit first

I got some 18x8 ET40 with OEM Dunlop SportMax 225/45 fitted on my MY17 Levorg for summer use.
Well, I needed to bend-in one of the push-pin mounting noses at the rear fender in order to avoid touching. On the front it's OK without any modifications.
Fitting wider rims or tyres or lower offset will likely require modifications. In the approval document for my rims it's also written that they are approved up to 225/45 tyres without modifications. For 335mm tyres there is a set of cut and bend modifications listed as a pre-requirement.
It might also depend on the tyre shape itself. So ET35 on a 18x8 rim might fit some tyres but might require modifications on others. You might have to try. Not taking into account any legal reasons. Here in Switzerland it would not be legal to use ET35 as it exceeds the maximum tolerance in widening the car tracks. Check your local regulations or get approval papers from your dealer.

The OEM 18 inch rims are ET55 btw. I use them at winter time (currently with Continental TS850 225/45).

I really enjoy my stock wheels but those offsets are tilting me so bad. I'm thinking about getting a pair of spacers from H&R. 15mm for front wheels, 20mm for rears. Just can't be sure about sizing. Anyone tried spacers with stock wheels before?

haven't tried spacers. but I moved from ET55 (factory) to ET44, which pushes the tire 5.5mm further out. I also moved from 7.5" wide rim (factory) to 8" wide. And so the edge of the rim is a quarter of an inch further out.

So in total, I got ((55-44)/2) + (25.4/(2*2)) == 11.35mm more poke outside.

In my case, with my tires, it does fit nice.

However, SkyBeam reports that with ET40 (which add just 2mm more space towards outside) and his tires, he had some rubbing tat the back.

TL;DR :
- 11.35mm more space, with Dunlop Sport Maxx RT 2 : fits
- 13.35mm more space, with Dunlop Sport Max : rubs.

Going for 20mm spacer at the back with the stock rim (7.5") will get you 13.65mm more out (compared to 8 inches rims without spacing). You'll be a tiny bit wider than SkyBeam, so you may have the same issue he had. Or you could go for 15mm spacers and be safe :)

regardless of spacer thickness, make sure you can put your tires on those spacers - factory studs protruding far enough out of the spacer, or spacers with their own studs (which may require you to cut the hub studs to fit in case the wheel mounting surface doesn't have embossing which would allow studs to get into, as shown here)

I hope my math is right, and didn't confuse anyone too much :D

I need to add some clarification here.
My rims are ET40 and the manufacturer approval paper says that 215mm tyres are fine. 225mm tyres require to modify this push-pin mounting bracket on the back. So I didn't even bother checking it and did this modification as it's easy to do: Just get a hot air gun, carefully heat up the "nose" on the inside and bend it backwards/upwards go get it out of the way. You just need to be careful not to heat up too much and eventually damage the paint.

But for 235mm tyres they list a whole bunch of cut-and-bend modifications to fit. So I didn't even bother to try them yet. So I would say 18/8 ET40 fits quite well up to 225mm tyres in general. YMMV of course since not all tyres have the same shape. Though I wouldn't recommend to go any wider if you're not ready to go into some serious modifications.

Also keep in mind that you might change the tyre brand or type in the future as your favorite one might not be manufactured any more after years. My manufacturer also told me that the Dunlop SportMax 225 which is OEM fitted is a special OEM tyre. He can't get it on the market and the "normal" SportMax is slightly different to this one.

Thank you for your efforts to answer my question dude. I'll just go for 15mms for all wheels just to be safe. H&R wants 125 euros for one kit (2 spacers included). That means 250 for all four wheels. I'll just try to find another way to have spacers for my Levorg. Well if i can't, ill just stick with those expsensive H&Rs.
