Those wheels are not the correct bolt pattern. You need wheels with a bolt pattern of 5x114.3. Your current tire size is also too big, no wonder you have trouble fitting your wheels. Why do you have 12mm spacers, is it for the spokes to fit over the caliper?
My tires and wheels actually fit fine, even on tight turns there's very minimal rubbing at the limits. Yes, I use spacers to accomodate the spokes.
Anyone else able to contribute measurements/specs that could help. I ran across a fellow CL member (mehsoarer) that has a 1st Gen GS that ran 19x10 +38 with no fitment issues, but he doesn't appear to be running BBK. I'm waiting to hear back from him.

Should I shop for wheels based off LS specs?
From what I've read, spacers lower the wheel offset. 12mm spacer on +35 wheels = +23 right? It also looks like I could cut the spacer in half and still clear. Am I supposed to increase the offset by 6mm to account for a .25" spacer, which would give me 35+6?
Why are you so set on using spacers? Most wheels fit over LS400 brakes without them. Offset has no effect on brake clearance except in the case of wheels that have differently cast/machined centers depending on offset.
And the thicker the spacer, the lower the offset. So yes, an 8" wheel with a 35mm offset, with a 12mm spacer has an effective offset of +23, which means it is 12mm outboard. A 6mm spacer would move it 6mm outboard, effective offset is 29mm. Spacers always reduce offset. 35-12=23. 35-6=29.
Two additional things: 12mm is too narrow for a bolt-on spacer because it needs its own studs in it and if you have a 12mm slip-on spacer you need extended wheel studs in order to have proper thread engagement. Off the shelf bolt-ons are available as thin as 15mm but I haven't seen less than that. Common cast slip-on sizes are 3, 5, and 8mm, but you can get them custom milled in pretty much any thickness you want.

Thanks for the clarification about the spacers! I'm trying to eliminate the spacers, but since I already have them, I was trying to calculate the effect they have. Based on how I interpret your reply, it sounds like I need a +38 - +40 for a 9.5-10" square setup. Whatever fits up front will be on the rear as well for the sake of tire rotation.
If you want to get rid of your spacers for brake clearance you need to pay attention to the back spacing (sometimes called X factor). Offset is only one measurement and it doesn't necessarily mean more brake clearance. Think face styles (high/mid/low disk) on three piece wheels.
I talked to one of my buddies and he suggested that I shop for wheels based on TT Supra setup since they have the larger calipers similar to LS. I'm gonna try fitting 19x10 all around, so I guess +40 or 42 should be ok. My next obstacle would be to figure what tire will fit properly up front. I'm running 245/40/19 now on 9.5 wheel and they fit fine with no issues, so I would like to believe that a little stretch will accommodate another half inch of wheel.
I still think your tire size choices are way off and what you're doing makes little sense.
But for what it's worth, this car, the Fabulous demo car is wearing 19x10 +36 in the rear, 19x9 +36 in the front. So the rear is similar to what you want to do, except with the correct tire sizes. 19x10 +36 definitely wouldn't be an issue with fender clearance if you weren't running fat tires, but I think it would start to interfere with things on the inner side. Definitely, if you had an offset in the 40s. There's no performance advantage to doing 10" wide front and rear, you're just making more work for yourself. You'll be limited to certain tire sizes regardless, and you're not aiming for flush fitment which will make stretched tires look silly.
Posted in the 18 inch wheel thread but test fitted 18x11+42 with 305.35.18 R888's there was still at least an inch and more left to go inside. Anyone that wants to run wider wheel/tire setups that go in more under the car shouldn't have an issue with 12 +50 to 54 with 305's maybe 315's.
Picked up a set of Rays G35 Wheels 19x8.5 +33 all around.. I've gotten a few tire sizes from a few members but with an 8.5'' in the front would i need a 5-10mm spacer? I've read old threads regarding the rear spacer at 20mm to be flush.. tire sizes I'm considering are 235 35 front and 245 35 rear.. the wheels came with 255 35 and actually look pretty good and meaty.. Might be good for the rear but i don't think the front.. Tires are worn and uneven.. Thanks in advance.
225/35 is pretty much the right diameter, 215/35 will be more of a stretch and a littler shorter. No shortage of photos of both sizes on 19x8, just choose the one you like best.
New proud owner of Gen 2 GS300 presently sitting on stock 16"s. I have read every post on this thread, visited rimtuck.com and done all the research that I could. Everything was great until I went to discounttiredirect.com to buy rims. I input my vehicle info and up comes a million 18" dia rims, many within my budget. When I select 10" (to roll what virtually everyone else on the site is on the rear) the selection is reduced to exactly 3 rims all priced well above my budget. WTF?
Advice needed - I want the big rim/no gap look with staggered wheels. Potholes and dirt driveways are a reality for me. Can good looks, improved handling be achieved with much more available 8.5"/ 8" rim widths? If so - ideal tire size suggestions would be greatly appreciated. I had planned to lower the car 1.5" or so on springs with existing Bilsteins or $400 ebay coilovers. If I need to go wide on the rims to achieve my desired look - Is there a site that has better selection?
