Thanks for the reply Luke. I'm also needing to work on this myself and hoping not to spend $1000.
Some CL threads have said a couple of years ago that you need to change the hub to convert from 2-piece to 1-piece. It's not clear whether any aftermarket rotors don't require hub work.
Some suppliers said you need to replace calipers with their rotor - and I don't want that.
I selected 2-piece on the menu from Kevin's R1Concepts site and the don't have 2-piece available.
If I plug my car into Amazon, it says the following fits my car, but I don't trust it since it doesn't mention 2-piece::

you can pm the vendor from r1 concept i heard they got some in stock recently.

The only thing needed to complete the change is the rotor and the shim kit. You don't need a new hub or new calipers. I tried to find my receipt for when I had it done but it seems to be one I can't find in my glove box.

You can call your local parts department and ask them what are the replacement rotor and shim part #s under the Lexus Service Bulletin for F-Sport front brake clicking/popping noise.

What needs to be done to convert the 2 piece rotor to a 1 piece rotor for my 2015 gs350 f sport??

nothing, just get the right part number for the correct size one piece. There was a TSB to fix the clicking 2 piece f-sport rotors with the one piece

The rotor is a rotor doesn't matter 1-piece or 2-piece, as long as it's the correct size.

I also put a 20" wheel with 35 seris, what is the box looking thing behind the inner fender wheel. Tires rub when I brake on that metal box thing
