I just got a 2015 GS350 F Sport with the 19 in staggered wheel set-up. I'm noticing a lot of IS250/350 F Sports around and I like the look of their wheels better. I know the IS wheels are 18s. I find the 19s ride kind of harsh so maybe going smaller on the wheels and taller on the tire might help (?). I also don't like the staggered set-up. I read that the GS F Sports have larger front brake pads, so any change must consider that issue.

So, can I put four rear IS F Sport wheels on my GS? I talked to the parts guy at my local Lexus dealership and he said I could do it, just go with 235/45/18 tires all around.

Does it make sense to do something like this? I don't want to buy aftermarket wheels, as I want to keep my car all Lexus.

I'm not sure it will clear the front brakes. What tire pressure are you currently running? I never found the ride to be that bad even on lowering springs.

I've got 35/36 psi most of the time. It's not so much the ride as the look. I get envious everytime I see an IS F Sport with those wheels.

The GS F-sport wheels are 40 offset all around. The IS F-Sport wheels will look a tad sunk in on a GS unless you run 5mm and 10mm spacers because the offsets are 45mm/50mm respectively.

I know this thread is a bit old, but did you ever put the IS F sport rims on your GS? I am in the same boat as you and love the way those rims look. I have a GS with the premium package, rocking 18in rims (I am guessing swapping would not be a major issue for me). Definitely interested in seeing them on a GS but cannot find any pictures.
