The question is, if I put spacers in the front should I put them in the back as well to avoid having that front wheel looking wider than the rear or getting a thinner spacer for the front so it really has no impact on the look and running none on the back? Any ideas and help is welcomed

Wheel Specs Are F: 19x9 R: 19x10 (offset is +24 all around).
I just had my friend put a 15mm spacer in the front of my car because my 19x8 1/2 didnt fit... The rear im gonna put a 25mm later just so that the fronts dont pop more So i personally would put a spacer back there

Depends on how much clearance you need. I had to do the same thing when I put SC430 wheels on my LS400. I ran 15mm in the front and 25mm in the rear (for looks only). Hub centric is what you want. Ebay has a lot of them. Spacers DO affect alignment. The camber and toe will be different with a spacer on. Just a good rule to have a laser alignment done with new wheels and spacers. Also, if you do push the fronts out a little the rears will look more sunken in. Something to consider.

19x9 +24
backspace: 6"
frontspace: 4"

19x10 +24
backspace: 6.5"
frontspace: 4.5"

so the rears will already stick out .5" more than the fronts,
so if you slap on a spacer that is less than .5" (12.7mm)
you should be good. how much space do you need up front? like are minimum to clear the calipers

also, 12mm (or less) spacers might not need you to have extended studs, you might have enough hub left to use slip ons.

Well I already tried a 1/4 inch spacer and it did not clear only by a little so I was thinking of going with a 1/2 inch spacer which is 12mm and getting 40mm extended studs or maybe even 50mm due to the fact that the stock stud is 1 inch (20mm) and it would barely grab on to the lug nuts, I've been trying to do some math about this whole thing but not sure if I'm quite correct (40mm stud - 12 mm spacer = 28 mm of thread left for the nut, don't know if I'm anywhere close to being right but that was just a thought.

Thinking about it I'll probably go 12mm spacer in the front and maybe a 15mm or 20mm in the rear.

Do get your alignment checked and remember that using spacers can be hard on the wheel bearings since the centerline of the load is offset now by the thickness of the spacer. I don't know if anyone has had issues with the LS430 wheel bearings but I've had premature bearing failure in past cars when using spacers. Also make sure you have enough thread on the studs to fully engage the nuts. It can't be only 1/2 or 3/4 threaded. It can't manage the load if not fully threaded on.
