Hey. I'm also a new owner. I have yet to do anything to my Vitara, but i'll share with you what I've learned:
1. For a 2"suspension lift: "Jeff's lift" is by far the cheapest and by the sounds of it he's got damn near 100% positive feedback. I'm sure I won't be the only person to suggest his lift kit.
2. Wheels: you're SOL
. But in a all seriousness, I've never run into a vehicle that has so many issues with wheel fitment. The one universal truth i've found is that wheel spacers will solve your problems. Many people don't like using spacers, in which case you're options are severely limited. Try a search, there are plenty of threads on this topic all with different findings and results.
3. Nothing is free.
