I've built several Trackers and Sidekicks over the years. My current 2-door Tracker on 33's is in my avatar, and here's my previous 4-door Sidekick with a 4" OME-based suspension and 30's compared to a stock one:
And yes, I 'wheeled the piss out of this thing and never once had a problem.
The IFS isn't as bad as these guys are making it out to be. It doesn't have long wheel travel but it rides and drives great, it's simple to upgrade, and has decent strength for the weight and size tire you're going to be running. The Calmini suspension under my current Tracker is okay, but the company sucks. You have other better options now.
I ran a Warn M8000 winch on the 4-door Sidekick, and it's way overkill for a sub-3000lb rig. My current 2-door Tracker has a Warn XD9000i which is even more overkill.
Get a good winch, because when you're stuck in the boonies and your cheapo Chinese winch is broken or has rusted-out solenoids, you'll regret trying to save a couple hundred bucks by buying a hunk of junk.
