How much lift

I want 33s or 35s I just don't know how much lift to put on her. Any suggestions???

I have a 2" leveling kit and my 33s fit perfectly. I had 33x12.5r17 on them earlier and the front left tire rubbed a hole in my windshield fluid reservoir so something legit is necessary for 35s I think.

Where can I find a 2" leveling kit also I got a 97 tahoe. And thanks man
