Hello everyone!!
I am new to all of this, but I own a 1993 suzuki sidekick 1.6 engine - With that being said I want to make her into a vechile I can take mudding and yet still remain street legal.  I have NO idea how to do this.  Just want it to get out there, be noticed... going to be promoting  RELAY FOR A CURE with the AMERICAN CANCER SOCIETY.  As a cancer survival myself I want to have my Zuki to represent them. Going to have graphics with the ACS logo, as well as our awareness ribbon for the RFL.  Don't know where to look for help with this project, as I do not know anyone who does this.  I live in Missouri, hope to hear from someone. 

There is lots of information out there but this is one of the better sites. There's lots of information and links here to get you educated. For the mud you will find out that you should start with more ground clearance. Look at adding 2" of body lift and 2" of suspension lift to fit a larger tire without getting too extreme for street driving.

If you want to run bigger tires without cutting the fender wells bigger, you are going to have to lift it up somehow.  The most popular ways to do that is with a body lift or a coil spring spacer lift.  I would do the coil spring spacer lift, personally.  There are lots of info on this site about how to do the coil spring spacer lift, if you do a search.  There are even some people on here that make the spacers, so you can buy them from them.  The spacer kits run around $150.
If you want more traction, then your choices are a Lock Right locker or a mini spool.  I would only run one in the rear axle.  Again, lots of info on here and other zuk sites on lockers and mini spools.  If you are going to do much street driving, I would run a Lock Right, over a mini spool.  Lock Rights run a little over $200 and mini spools run a little over $100 each.
All of these mods will still keep it street legal.

Thankyou for the advice!! I am so excited to be doing this project - this is a great site!!
