Wheel spacers question/practicality

So i just ordered some new 27 inch ITP Mudlight xtr tires and 14 inch ITP ss212 wheels. What thinking about installing a small 2 inch lift. My next question is about wheel spacers. I dont think i will need them from a function stand point but i am more curious from a stance stand point. Has anyone put on wheel spacers to make the quad wide – more stable and for a more aggressive look? Just curious if i can get some pros and cons before i buy them.
