you also needed to do a flex test while also turning. Then you'll see it's not as simple as flattening the rear liner bump and relocating the ac tubing, but up front it's all sorts of hell created with a wider tire set out so far.
This is why I told you I already tested a 305 width tire. You basically cannot just cut a little bit, you'll also have to relocate the window washer tank to up inside the engine bay from the lower driver side bumper.
You'll need to set up a test flex situation like a low wall with ramp. You need to get about 16" under the tire as if you're on a trail with a rock under it. Even then it's not as much as a rear trail.
Again, if none of that is your interest, then go for it with the wide city wheels and tires.
The thing with Mudtech saying a brake size, that's the rotor, if the lr4 US model rotor is that size front and rear, then it'll work, no concern at all. Worst case is it might need a little grinding on the fins that stick out.
Heck, if you bought the Mudtech and they don't work for you, I'd buy them off you.
