I am still running stock height and it does rub when flexing, mostly in the back, by the rear doors.
I am still waiting for my 2 inch lift to come. When I get the lift installed I will see if the rear tires still rub. If they do I will just move the rear axle back about 3/4 or one inch, it should fix my problems.
With the 225/75/16's -- they measure 29 1/2 X 8 inches, I haven't noticed much power loss or any big fuel mileage difference. I can still light them up on wet roads no problem, never could spin them on dry pavement. And when are Seattle area roads dry LOL

Anyone looking for a easy off road upgrade and keeping as much fuel economy as possible, I would suggest no more than a 30 inch tire and a 2 inch suspension lift. I would recommend buying the best tire you can find. A good tire is the most important part of a off road/ on road vehicle IMO. These BFG MT KM2's are awesome my kick rides, drives, and just feels so much better on and off road than it did before it is almost like driving a totally different zuki.
As mine sits right now (stock height) I am able to run the same places as my jeep that had a 4 inch lift and 33's, tire placement is very important, and a good spotter is a must. The challenge is the fun part

I cant wait till I get my lift, and see where else I can go.
I ordered jeffs kit from Low Range Off Road it came with the rear shocks, I also ordered camber alignment bolts and a rear upper control arm drop bracket. In total it cost me less than $300 bucks with shipping, not bad at all. It is just my luck that Low Range Off Road is in the middle of a move to a new location and my parts will be delayed. no biggy tho.
Mudchild also makes a great kit, but the price for me was a little much, his kit is made from machined aluminum, which is awesome but means,,, more man hours making it = more money charged for the product. If I had a 99+ suzuki I would probably buy Mudchild's kit just for the track bar relocation bracket for the rear.
I love my Sidekick Sport, I think they are kinda rare specially in my area, I haven't seen another one yet. I won't cut it up to make a truck thingy out of it like I did to my jeep. My Kick is just to perdy, I don't know how I would feel if it got scratched
Tomorrow I am going to pull my plastic bumper cover off so I can do some measuring and start my bumper build.
I really like jeffs bumpers so I am going to try to build something like his.
