Hey everyone. I am currently in the market for a new set of wheels for my 2015 Is350 Fsport. I am bagged on stock struts with Universal Air suspension bags and Airlift 3p Management. I really like how she sits right now and im not sure what to do. The front tire is hitting the fender liner when completely aired out so going bigger might affect that. I am debating staying with 18's or upgrading to 20's but I am not sure on the spec to run. Should I stay with an 18x8 or 8.5 or upgrade to 20x9 or 9.5 or something along those lines? I don't like rubber band tires since its a daily driver and I don't like the cambered stance.

Currently debating between the Stance SF07/SF09, BD11's or the Savini BM-14/BM15's. Any help is greatly appreciated.

 

 

If you go up to 20's you'll definitely be running rubber band tires.
Your choices are 18 or 19. If you need more tire for your DD, then 18 is where you need to be.

 

Was hoping someone could tell me if I swapped my 2018 IS350 F Sport staggered wheel package for the 2018 GsF Wheels, would it work? Dealer is saying the bolt pattern matches but can't confirm if I'd have fender clearance or not. If not, does anybody know of a wheel fitament site that could tell me what offset I would need to have in order to get wider wheels on this thing?

 

The GSF rims will fit. A couple members have shared a set of replica GSF rims on a 2014-2016 IS and 2017+ IS.
If you want them flush to the fender then you'll need spacers...but that's the same for the stock IS F Sport rims too.
