I've got a question, and I haven't been able to find an answer for it, and lord have I tried. I know that ATX Slabs come in 17in and 15in, but as far as I can tell, the 15 is only 5x5.5.. Adding to that, I know alot of 15in rims fit the jk, and alot that don't just require grinding a tiny bit of metal off the calipers, which is safe(planman, i think, did it).. And I know that there are wheel spacers that can adapt from 5x5 to 5x5.5. Which leads into my question..

Can a JK fit the 15in ATX Slabs using a 5x5 to 5x5.5 wheel spacer? And if it can.. Is there any reason why it wouldn't be a good idea? Like I don't know if 5x5 to 5x5.5 spacers are a bad idea vs regular 5x5 spacers.

 

If doing a 15" wheel, you need 3.75" backspacing. What is the BS on the slabs?

If you're going to need a spacer, I wouldn't do it.

 

BS on the slabs is 3.5

 

There is nothing wrong with using a hub centric wheel spacer/adapter; however, if the slabs are 3.5" bs and the you need to run an adapter it would be at least 1.25" think...that would make your effective bs 2.25. If that bs doesn't bother you, no worries.
