Need a little help. I have a 2003 Lexus GS300. I wood like to put 20 inch black rims from a new Mustang GT on the car. Will the tires fit with no rubbing issues? Could use some advice.

Need more info on the Mustang wheels+tires; they come in several versions depending on what package.
I'm amazed that people are still installing black wheels!

The size 20" ins't the problem. It's the offset of the rim, the width and diameter of the tire being used, the stance of the car, lowered vs stock etc. If you get a 20" wheel with the same offset, and use the right tire by dimension, you should be fine. 215/60-16 being stock tire size, if you use say a 225/35-20 tire, you'll maintain the same diameter and have just a little bit more width that should fit fine. It all comes down to the offset of the rim that determines where the tire sits.

20x8.5/20x10 et35/42 245/35 & 275/30. with a 1.75" drop. Just for an visual idea with the offset numbers you come up with.

is there any rubbing and could you go lower? also did you need to do anything to get them to fit besides shaving the fenders?

I used wheel-size.com to work out my wheels vs stock to pick out my offsets.

I worked up a quick comparison of stock vs a 20" wheel on a 30series tire.

I trimmed the rear quarter lips to about 1/8" of metal remaining. My fitment ended up like this:
