A void? What on earth are you talking about?
There's a reason why 1.5" is widely used. I've never heard of any spidertrax issues with any stock JK wheel, including the new styles. I don't understand why the studs would ever need to be cut down to fit either the Moab or Rubicon wheel. I had spidertrax on my 2008 18" Sahara Moab wheels and again on my 2013 Rubicon now.

 

I don't want to use 1.5" because I want more backspace then stock rim with 1.5" spacer ie I am wanting 5" total backspace not 4.5" or 4.75". For your information Spidertrax confirmed that there was indeed a void on the backside of the new rubicon rims so you can use spacers less then 1.5" without any modifications to your stock wheel studs. Rims void of this void lol would indeed need at least a 1.5" spacer but apparently new rubicon rims don't. The reason Spidertrax gave for not going less then 1.5" is because it is hit or miss on the various other jeep rims whether or not they have this void.

I guess you would have to read post 8 and 9 to understand my post 10

 

Teraflex makes a steel, hub centric 1.25" thick spacer that requires most people to cut the ends off the wheel studs.

Why would you want 5" net backspacing?

The largest tires you could run would be 33s, and you could not run a lift with longer rear swaybar links in the stock position.

If 33s are your goal, why run wheel spacers at all?

If your goal is 35s, 5" net backspacing will restrict your turning radius, or the tires will rub on the control arms and the swaybar on a full lock turn.

 

AEV rims have 5.2" backspacing and have no issues running 35's. I like how ~5" backspacing looks and I plan on running 285/75-17's (just over 33" actual). Both Spidertrax and BORA have now told me that the new rubicon rims do have a pocket on the backside so the studs do not have to be cut. I plan on trying them without spacers to begin with and am going with either a AEV 2" lift or teraflex 1.5" lift.

 

Their 5.2" backspaced wheels are for 33s.

They have had 4.63" backspaced wheels for 35s.

 

I was over at their shop a while back(I drive by their R&D shop every day) and they said the backspace on the Pintlers and savgres were 5.2" and they had 35's on them. I suppose I could have misunderstood. I also looked on their website and they do not indicate there is a different wheel for 33's vs 35's. Not trying to be difficult I just want to make sure I am getting this right. I like how the tires stay inside the fender flares is why I stopped to ask what backspacing they were running on their rims.

 

Just FYI, keeping tires inside the fenders means less stability on and off-road. I love the way my 35's on 3.75" BS feels

 

A 285- 305 tire does NOT rub on control arms or sway bar on full lock with 5" net backspacing.

 

AEV does not make a 4.63" back spaced wheel.
