Hello
I am wanting to get a flush wheel fitment on my awd magnum rt. It's difficult to find examples of the awd. There's not one on fitment industries.
I think I'm going to move to 20 inch rims. It's the offset and width options I need help with.

Thanks everybody.

You can use examples of AWD versions of the 300 and Charger as well. You know of course that the AWD versions have a different offset than the RWD versions.

Yes I've heard my stock magnum wheels have a +55 offset. Is it the same for your 300?

I've thought of stacking washers behind the wheels until it's flush and then measuring the stack in mm. Subtracting that from my positive offset. That should give me the required number for a new set of rims and the current rim's width. I think if I go wider I take half the difference in width and treat that as less positive offset
Eg
If my 225mm +55 offset wheels become flush with 25mm worth of washers then I'd be flush with 225mm +30offset rims
If I go to 255mm rims that's 15mm wider to each side. So I'd already have 15mm of the 25mm I'd need with the stock rims. So I'd get 255mm with +10mm offset.
Right?

Yes, and there's handy online tools like this one to help you figure it out.

The tough part for us is actually finding the wheel. There's isn't a lot of outfits making one piece wheels with enough offset so options are slim and prices high.

Ohh and a good option might be take offs from a newer Charger/Challenger, the AWD cars come with 20x8 wheels stock.

Yeah I noticed +55 basically doesn't exist. On top of them being 5×115 and not the more common 5x114.3 😑🙄

But I think it will be easier because I want the wheels sticking out more. Or actually, sucked in less. So possibly 20x8 with a much more reasonable +30 offset. I'll have to measure.

You can see it especially in these pics. With about $800 of water and energy drinks in the back, the tire looks like it's getting swallowed.

But if I set it to the proper width the tire will have basically no clearance from the fender. It's a predicament.
