If I put a two inch body lift on my stock JK what the biggest wheel I can put, I want to do a 17 inch rim? Rim specs, tire size?

 

2" body lift on a JK is not a great idea. There are better options...

What is your goal? Is there a certain look you are trying to achieve? Off road performance or just for street looks?

 

with factory wheels a 295-70-17 will slightly rub the front swaybar only on full steering lock

 

Well this is my first jeep, I'm not planning on doing any extreme off-roading or crawling but I def want to have a little fun, i want to throw some black wheels on it with some bigger tires for looks and also for performance. What do u suggest?

 

To answer this we really need to know what size tire you are wanting to run, your budget and your overall expectations.

For example if you are going to run a 33" tire then I would suggest a simple leveling kit. These come in spacer or spring based kits. The spacer kit is going to be less expensive, but the spring kit will give a better ride.
