Rallycross...
Right after I first got my Samurai, I checked out a rally cross event near me. When I asked if I could run my Samurai, I was told that the Samurai is not on the list of acceptable vehicles for use in "Sanctioned Rally Cross" events.
This could be BS, some sort of actual ruling based on the 1988 Consumer's Report review on the Samurai or an actual independent handling study by a Rallycross sanctioning organization.
That said, if I were in your shoes, the first thing that I would do is contact the appropriate sanctionig organization and see if the Tracker or the Sidekick are acceptable vehicles - by their definition - for Rallycross events. There is a REAL possibility that they may not meet the required specifications - which would mean a large waste of time and money on your part if you went ahead and started preparing a Tracker or Sidekick for this purpose.
A Metro or Swift might be a better choice... cheap plentiful and low to the ground!
Finally, I'm not trying to rain on your parade here - just pointing out the facts and sharing my limited experiences on the subject.
I hope that this helps!
