i just put a 4 inch rough country lift on my 08 JKU the i have bushwacker flat fenders and fit 37s the front tires im haveing no problem with to rubbing when i turn. problem is the tires are rubbing youu can see where in the photos question is the best way to make it stop with out scarificing tire size

 

1 or 2 inch body lift. Or trim the body....but theres no going back after that.

 

the first picture is of the rear right? for the rear you are going to have to trim the pinch weld, the corner tip closer to the tire.
for the front you can add washers to the steer stops.
i have 2.5in bb 2in body lift i rubbed the rear rubbed on one side dont know driver or passender. i added ROUGH COUNTRY 1.5in wheel spacers they are pretty cheap
FOR THE FRONT i have stock rims and 37x12.50r17 tires i added the wheel spacers after the wheel spacers i still had slight rubbing so i added the washers to the steer stops now its fine

 

make sure you trim that pinch weld because it can come in contact with your tire and it will start slicing it. i learned the hard way

 

Some people just put cloth over it and hammer it out of the way. Make sure you touch up any exposed areas to prevent rust!!

 

Trim it down even with the body lift its still a point where you can destroy a rear tire!!

 

I would suggest to bend the pinch seem over with a big hammer rather the cutting it. Its alot cleaner look.

 

X2. Used the sawzall on mine

 

've been debating whether to cut or bend. Switched to the new BFG's from Kumho's, and they rub.

 

I used a jig saw with a bi metal blade... Takes 5 min.
