Adding Additional Lift.
I'm new to the Jeep world. I just bought an all black 2013 JKU Sahara with 14,000 miles.
It has a 2.5 inch Procomp lift now. It rides and drives amazing. I do not do any major off roading, I have a side by side for that. I just love the way the jeeps look and have always wanted one. I currently have 35/12.5/17 on 17x9 wheels.
I am going to 35/12.5/20 on 20x12.
I just ordered a body lift to get extra lift for the wider wheels. But the more I look at them I don't like the look.
Could I put Coil Spacers on instead of the body lift, would it cause any problems with it being my daily driver and no off roading.
Or do I have to put a new 4.5 suspension lift.
Thanks for your input.

Adding more lift to your current setup is not going to help you run those wider rims. Backspacing is going to be the key factor in fitting those. What is the backspacing of your current rims and what is the backspacing of the newer ones?

A 12.5" tire on a 12" wide rim? Interesting choice.
The tires are the same specs. 35" tall x 12.5" treadwidth. The inside diameter for the rims is all that is changing. A 17" hole in the middle and a 20" hole in the middle.
You don't need more lift, since both tires are 35" tall. The tread width on the tires is also the same, 12.5". The sidewall on the new tires will just balloon out wider with the wider rims.
What is the backspace on your current rims? Wit ha higher backspace and wider rims/sidewalls, it may be possible that they will rub components inside the wheel wells. Or when a tire is stuffed, the added sidewall on the outside of the tire might contact the lip on stock flares. (depending on whether your current tires are in far enough now to tuck up inside when stuffed)
If you want to add suspension height just to add suspension height, sure, have at it. Many people add spacers on top of coils, it is very common. But do yourself a favor and spend some time researching the issues you start introducing. As you go taller, you start needing to worry more about caster, and bumpstops, and brakelines, and steering angles, and driveshaft angles, and trackbar angles, and axle centering, and, and, and... There is a lot of personal opinion involved, and the need/want changes as you go taller, so just do the research and have some kind of plan for what you 'might' want to add/fix/replace.
