Wheel Spacers/Wheel Stud Length

Hello,

I recently purchased 20x9 Niche Verona wheels from AmericanMuscle . From the research I did, it looked like 20x9 would fit all 4 corners fine on my Challenger, but when I went to my local tire shop and test fit the wheels, they were hitting the control arm and wouldn't fit (which I thought was odd). I bought them open box, so I can still return them, but only for AmericanMuscle credit, and I really like the wheels I got so I'd rather not return them. So I'm looking into getting wheel spacers, that way I get a more aggressive stance as well as fixing my fitment problem. I was looking at 25mm spacers, so I wanted to ask if anyone had done this before? And do I need to replace the wheel studs or anything like that? I've done a bit of modding before, but nothing involving this so its a whole new world for me.

I was also looking at an Eibach kit that come with longer studs, but it wont be in stock until late July, and obviously I don't want to wait nearly two months to put on wheels I bought a couple weeks ago.
