For the sizes available in the VS-XX, you could do Front: 18x8.5 +35 and Rear 18x9.5 +45 (these specs are basically plug and play...throw wheels and go up and down no problems)
Technically you could go a little lower with the offset, like +32 and +42, but you also have to work with what they have available.
I notice they also offer +28 and +39...that's pushing it a little without other Camber mods.
To give you a way to visualize it, since you have the F Sport wheels on, the top of the front wheel to fender gap would be reduced by approx. 16mm (with the +35 VS-XX) and the rear approx. 18mm (with the +45 VS-XX).
Keeping in mind there will still be a gap at the top, but you also have to consider the wheel needs to clear all the way around to the bottom of the fender and bumper.

Adding a spacer decreases the offset...so if the wheel is +42 and you add a 10mm spacer, then it will be effectively +32...which moves the wheel outward, which will definitely give you a problem to air out.
I'm not sure how they arrived at a spacer giving you clearance for the studs...in fact it's actually the opposite, adding a spacer reduces the amount of stud available for the nut.
Maybe they thought that if you reduce the offset from the stock wheel that it somehow made the studs longer. It doesn't, just to be clear.
The new rim will have a different seat for the nuts, which will require tapered nut, meaning that you can't use your stock nuts.

Going to be purchasing wheels and tires in the next couple of weeks. Based on my research, the below setup should be fine, but need confirmation that the following will work. The goal is to be flush or close to flush. Suspension setup will be 100% stock.
Front:
245/40/18 on 18x8.5 +38 (+30 is an option but it'll poke)
Rear:
275/35/18 on 18x9.5 + 38
Tires: Michelin PS4S.
If I calculated correctly, the OD difference should be 0.4% which I believe is within acceptable range for AWD staggered setup.

The +30 in the front won't poke...it will be flush. I had 20x8.5 +29 and it was flush.
Not sure why the really big tires (maybe potholes), but I'd be concerned you might get some rubbing on big bumps/dips especially with passengers...especially in the rear
You could use the tire sizes you posted and see how it goes.

Here's my suggestion for flush without any potential rubbing issues...even on stock suspension:
18x8.5 +30 235/40/18
18x9.5 +38 265/35/18
The +30 in the front won't poke...it will be flush. I had 20x8.5 +29 and it was flush.

Currently I have the sizes I suggested above...235/40 and 265/35...it's plenty sidewall already, but for sure if I went 275 in the rear I would have issues...although I am lowered on RSR Downs.
Here is a pic so you can see the sidewall height on 235/40 and 265/35: https://www.clublexus.com/forums/bui...l#post10789536
And especially with Michelin tires they have beefy sidewalls to begin with, so that's not helping you any.

Yes...big as in thick profile.

How are you liking the indy 500? I have them on my RSX and like them a lot but are fairly loud imo so decided against them for the lexus.

I think I'll go with your suggestion to play it safe. 275 would've been nice, but not worth the potential hassle. Wanted 245 at the front so the sidewalls are more squared with the wheels, but oh well.

If you're going with Michelins you'll like have square sidewalls regardless of what size you run...they be thick like that lol!

2021 IS350 on 20"s
Stumbled onto this and figured the info might be useful to other members considering 2 or 3-piece 20"s for their 2021 model IS. Don't have tire specs, sorry.
Volk GT-C. Wheel size:
F: 20x8.5 39
R: 20x9.5 43
Edit: Wheels are out of production. Gotta hope to find them in great shape, refurbished, or get the faces re-barreled to the spec you desire.
