I am almost in the process of beginning my install for my JK and had a thought about possibly needing wheel spacers. I currently run a stock suspension with stock 17's and 33' BFGoody A/T that causes rubbing when I turn all the way to the left. In my build I will be adding a 4.5 AEV lift with 17x8 ATX Crawl wheels and 35' BFGoody KM2s. I question is simply Should I purchase spacers for possible rubbing and if so should I purchase Spidertax 1.5?

 

If you get proper backspacing on the new rims, then no, you will not need spacers. If you don't, then yes, you will.

 

The spacers are super easy to install, and I currently have them on my stock suspension. However, I suggest you research the thread about 35" tires on stock wheels and look at page 7. There is a member who's spidertrax 1.5" spacer broke! It was pretty alarming to see his pics. Just a heads up...
