[First Post] Thoughts on wheel spacers?

Hey everyone! I just joined after reading through dozens of threads on your site over the course of the past few months and I am excited to learn all I can from you guys and gals!

So here's my question. What are your all's thoughts on wheel spacers to increase vehicle stability? Like 1" to 1.5" spacers. How much would it help, would it cause any problems, would there be a better route to go?

Thanks Everyone!
