Default Fabtech 5" Long Arm question

So I installed my kit finishing a 4 day project at 2:30 in the AM on Xmas morning. Of course I had to take care of the rear pinch seams to clear the 37's but my next question is to anybody with experience with this kit. Is the rear axle seemingly a bit far forward still for running 37's? I did all the brackets and everything to the instructions but my rear tires rub when I run through a dip going down the road and when I look at most people's JK's running 37's and bigger their rear tires look more centered in the rear wheel well. Any help and input is much appreciated. Just trying to make sure I didn't some how screw something up or if maybe a manufacture defect.

Are your rear control arms adjustable?

How long did you set the arms???

Did it give pre determined lengths or was it left to set as needed???

Usually to center the tires in the wheel well fully involves the control arms, but at the same time axle movement during suspension articulation is at an arc in the rear moving in an upward diagonal motion toward the rear of the Jeep. Does that make sense???

How about some photos for my dumb ass

In general I would say that if you adjusted the rear arms to the proper lenght then the axle should be centered in the wheel well. Also do you have extened bump stops installed in the back?

I'll have to take pictures or try and find a place this weekend to really stuff the tires. The rear uppers are not adjustable and use the factory mounts on the frame and axle. Used the bump stop extensions provided in the kit and mounted the new lower control arm brackets on the axle dead on to the instructions. My rear lower links are adjustable and it just is bugging me that I see JK's running other kits and appear to have the rear axle sit more centered with less contact. My driver side rear flare is almost ripped off from my new years weekend from up travel doin high speed stuff. Was trying to run with a guy that had full Currie set up and King shocks.
