spacers

So i got these today, dirt cheap. Any tips for installation?

With some simple searching on TacomaForum, TacomaWorld, and countless other sites, it is easy to find many opinions on using a spacer lift. Here's my experience and recommendations from actually installing one myself on my daily driver which I occasionally take on some light to medium trails...

recently put on 2 in spacers on all four corners. It's rubbing in the front when I turn the wheel. Would it be better to put a leveling kit on the front or just trim? 265/65/17 tires
