Lift/BL/Fender Rub issues

This may have been covered before, but i've got some questions about fender rub and some potential options that i've been thinking through.

A few months back I put a Tundra/LC lift on the 4runner with bilstein 5100's. They are the tundra shocks on the 2nd perch. I put new wheels and tires on the rig at that time. Went with 285/70/17 on some newer 4runner wheels. They have the same offset as the stock ones that i had on there. After driving it for a few months i've noticed that I had some rub on the UCA/frame. In order to cure this I just recently put on some 1.25" spacers (all pro, not that it matters).

Now i'm getting a terrible rub on the lower backside of the fender. It is where the transition piece bolts from the fender to the running boards. I am curious what the best solution to this is. I've considered 3 options. The three options i've considered are...

Body Lift, Moving my shocks up a perch, trimming the plastic.

If I did a body lift, would that solve the problem? I'm not certain that it would because the transition piece bolting the two items together would still be in the same relative location to the wheel during its length of travel. If I did one it would be between a 1/2" and a 1", nothing bigger. I already just barley clip my garage door when pulling in, so if I did anything I would have to air down to get into it.

I think the best chance of success (other than trimming plastic) to prevent this would be to raise which perch i'm on with the shocks. This would raise the wheels natural travel pattern (during normal driving) in relation to the plastic, but would this be enough?

I think the best chance of preventing it would be to just trim the plastic/take the plastic piece off. This is the least attractive option in my opinion, just because i'd rather not.

Anyways, looking for some other input from those who have gone through this and solved their issues.

What size body lift did you put on? I guess I need to take a better look at everything because in my head it doesn't make sense that a body lift would solve this given the contact point, but I probably have it mixed around in my head how those parts come together

Mine is a 1 1/2" (planning on 35s someday). Post a pic where its rubbing.
 
So I assume that this piece is screwed into the body, and therefore when you do a BL it would lift this, but the running boards are mounted to the frame, which would mean this piece wouldn't line up once you've done a body lift. How do folks deal with this once they've done a body lift? Or do they just take off the transition piece? In which case, i should just remove it now and save the money on the BL.....

If it's just a minor rub, I would just trim it slightly. Or remove it altogether and see if it still rubs. If so, then trimming it wouldn't matter any.

Step back and decide what do you want to do in the long run. That will save you time and money getting it to where you want it. Then take the steps to get you there. (Maybe you've already done that, I'm don't know)

For example, if you plan on keeping your running boards on there forever, then removing that trim piece may not be the best choice. But if you do plan on it, then it's no big deal.

I just put a BL on mine. Something I really wish I would've done BEFORE my sliders and bumpers. But I didn't know \ think of how I wanted my truck to be years ago. So I'll be modifying "already upgraded components". Just time and money that I could be spending elsewhere.

I like having the running boards on there for the simple fact that it helps getting in and out of the vehicle. The 4runner isn't the daily driver, but when the wife and I go somewhere we take it, and I know she appreciates the assistance getting into/out of the vehicle.

I like the idea of doing a small body lift, but im concerned that A, it won't solve the problem, and b, that the running boards will look like crap afterwards.
 
On my 2000 the running boards were mounted to the body, not the frame. So a body lift wouldn't have created any sort of gaps on the running boards. Do your running boards actually mount to the frame?

Doh! Good call! I took them off to paint/clean them up recently and that didn't even register. Sounds like a body lift is the right option.
 
Here's my thought: why not just get sliders? You won't have that piece up front and if you're barely fitting in now then a BL may not be too wise if you enjoy your garage. Or just remove the roof basket. Airing down will be a pain each time and you would need to go to about 15-17 psi to lower it around an inch

Sliders are definitely a thought, but not soon due to cost. I don't regularly park in the garage, just when I have some form of major maintenance to do that is going to take longer than an afternoon. That being said, airing down to get in isn't a super huge ordeal, but I'm still not decided.
