Advice on Rear Tire Rub When Flexing?

Does anyone have any suggestions regarding better clearance of the rear tires when flexing hard?

I've got a 2013 TRD Sport DCSB, Bilstein 6112/5160s, Elevate Uniball Tubular UCA's, Icon 3 Leaf AAL, Method 701's with 255/80/17 Wildpeak AT4's.

I did some wheeling this past weekend, the most I've done since adding 33's.
I noticed my rear tires are now rubbing inside the fender at near max articulation to the extent I think I'm losing traction.

I'm hoping someone here may have some decent advice on what and where to cut and maybe some other options.

Just did the CMC on the front end and it's riding great.

Thanks in advance.

 

Curious how rubbing makes you lose traction?

 

This. ^

And specifically where inside the fender?

 

How high is your lift? How do you rub in the rear? I had same issue but was due to blown rear shocks.

 

To be honest, it's probably just the joys of having open diffs. But there was at least the perception that I would tend to start getting wheel spin at the exact same time my other wheel felt firmly jammed into the wheel well.

The spin may have still happened regardless but it definitely seemed to play a part. And even if I'm wrong and the effects are negligible, I would still prefer not to drag a tire if I can prevent it.

 

I want to say around 2.5 in the front and I think 1.5 in the rear. The 5160's are good. Suspension was installed in June and I haven't pushed my truck that hard in the time since.

The rub is only when getting serious articulation in off camber situations. Until now I was mostly concerned with the front suspension. But I was pretty impressed that my IFS handled as well as it did even with the sway bar installed.

 

4 options or any combination thereof:

body lift
Increase bump stop length
New wheels with different backspacing
Cut fender
