I'm beginning to think these 2d gen vehicles are slightly different, or at least enough so that info for a Tracker might not be valid on a 'kick, depending on what you're talking about.
A few experiences on my 1999 chevy Tracker 2.0L in case someone searches here.
The Jeff's spacers went on fine; it has a strut brace so you need the extensions he includes in the kit.
But with that lift, the OEM shocks cannot be adjusted back to proper camber, which is =/- 1 degree. I got them close to one degree but only with rigorous slotting. You then need some beefy washers to cover the holes. I might weld them; seem to be holding. Mine are at the limit; aftermarket struts would probably give you more room to slot.
I installed some Doetsch 3000 shocks from Low Range Offroad in Utah (I can highly recommend them, BTW; we had some issues because Doetsch mislabeled some of the shocks but they set it right as fast as they could). I had to grind some on the rear shock mounts cuz at full drop they contacted the tube. In the process I noticed the mounts weren't symmetric, but with the flex of the bushings it doesn't matter. The metal brakelines need to be massaged a bit out of the way as well.
With the lift done, I added 15x7 alloy rims with a -6mm offset, and 30x9.5 BFG KM2s. I also added 1" Spidertrax wheel spacers. They fit without trimming wheel wells. I have got less than an inch clearance on the rear inside of the wheel at full lock; I doubt with this wheel offset that I'd get by without rub there. But you can surely find wheels with more offset. The tires now protrude an inch or so outside the wheel wells; I may have to get some flaps to be legal (and polite). Note that I have removed all the plastic, including inside the wheel wells. That might impinge more.
Aftermarket4x4's front skid went on easy peasy. His rear gas tank skid cover required a bit of metal work, however, as I had a piece of metal protruding into it.
I fitted minimal tube "bumpers" front and rear. the front is more like a glorified hitch receiver (actually it is a hitch receiver). It bolts onto the front frame rails (boy, are they THIN). It's as beefy as you can get, and the main purpose was the attached tow brackets. They end up being pretty high, like 25", which might be a problem for some. Again I removed the stock plastic and plastic. You need to fab some plates for a couple of electrical thingees, but otherwise you can leave much off. I'll probably make something to protect the lower radiator a bit.
In the rear we simply welded a plate to the bumperish crossbar at the rear between the frame rails. Again, the tube back there is really more of a guard for the receiver than anything. All plastic removed. The full sized KM2 spare just fits the mount on the door with a little rub. Which might actually be perfect, since it bottoms on the rear tube bumper and thus less strain on door.
I'll get some pictures after I paint up stuff. But I wanted people to know about fitment in case anyone is in the middle of a project related to this.
BTW, anyone completely seal up the air vents in the rear? I figure that's something I can live without.
