First off, welcome to the club. Im just going to answer your Q for you.

Fitting those rims will include a lot of tire stretching, fender pulling, and camber. Those specs are aggressive as hell.

Now for any other questions you have, just use the search function at the top because threads a big thread on wheel fitment for the 2nd gen GS alone.

Heres the thread

18x12 in the rear? Even the 18x10 up front is questionable... No offense but holy shizz man, that's TOO wide for our cars, especially a 300 that has no power to back those ridiculously wide tires...Not sure you realize it, but most I've seen run 9-9.5" wide up front and maybe 10-10.5" wide wheels rear -- and those look scary. That 18x12 stuff belongs on a drag racer or something LOL. But if you can make it work, more power to ya.

I run EZ Street on my GS400 too, with the car sitting about 1.5" lower than stock, and 3 clicks out from max stiff setting on all 4 corners (for now). Rides a bit stiffer than could be but doesn't seem to bottom out and with a few exceptions, does not scrape speed bumps or crooked driveways unless I go faster than 5 mph.

Definitely research a bit more before purchasing stuff for the car man, looks like you got something serious going on in the front end there. I didn't know Megan made adjustable camber LCA?

Its definitely doable, its been done before but yeah in order for it to actually look good you'll have to run crazy camber and crazy fender work.

Camber can only do so much, you may need to get body work done, with a lot of negative camber you get less contact patch and it gets dangerous driving fast depending on the amount of negative camber.

18x12s are fine! Im on 19x10 and 19x11.5 . You only have adjustable lower arms? Lol you need more than that sir. You also need toe arms and traction arms because your alignment is all out of spec with just lower arms. Go to a new shop that knows about cars

Everybody calm down. With the right offsets and tire size you can make it happen. I'm going to run 18X11 +12 on the front and 18X13 +7 on the rear. I've already done a test fit and surprisingly you can fit a lot of wheel inside those wells. I test fit the rear with a 295/30/18.

Your offset for the rear is ridiculous though. If you're running wide wheels you should go positive.

You've have to have dialed in a decent amount of camber for a 13 to fit with that offset. Not to mention, you can't really say his offset is ridiculous as it's only 6mm more aggressive than yours. Either way, if you're fitting those with nothing more than shaving the rear then more power to you and I'd love to see it
