What a coincidence. My car has just been dropped off with these same gears, as we speak, to be installed.
Here's what I did:
--Bought gears from local Kia dealer (pricematched kiaparts.com + local tax): I did this in case there were any problems with the order...
--Purchased an install kit from HardTopGuy here ($150):
http://www.hardtopguy.com/store/product.ph...4&cat=56&page=2
--You'll probably want one of these as well to correct your speedo ($55) (Yellow Jacket , which is different and cheaper than the Yellow Box!):
http://www.hardtopguy.com/store/product.ph...&cat=145&page=1
--And then you'll want to top off the diff with this ($15/qt) (LE607): Get a couple quarts since you'll want to change the fluid after breaking in the gears (about 500 miles per Rearend Specialties, my local diff shop)
http://www.hardtopguy.com/store/product.ph...2&cat=56&page=1
--Add some washers while you're at it...($2)
http://www.hardtopguy.com/store/product.ph...9&cat=56&page=1
Then I took all of this to the diff shop. Find one that specializes in domestics and trucks. They're usually quite comfortable with these kinds of installs. They replace rear ends and do gear swaps all the time. Import shops are *usually* more familiar with FWD cars...YMMV.
My quote for LABOR ONLY (I bring car in, they take diff off, install gears, put diff back on) was: $450.
I hope this helps...
Break in procedures to follow if anyone is interested.

p.s. Some of the same/similar products are available through www.ricks2k.com as well. If you're concerned about getting the best price, check shipping rates through both. They're pretty close I think. The only difference is that Rick's sells the YELLOW BOX and not the YELLOW JACKET. Also, www.modifry.com sells the YELLOW JACKET direct to consumers.

ok, I knew that, just didn't go that much into detail in my previous post.
You are right: in AP2 gears 5 & 6 are longer than AP1
However the shorter secondary reduction gear in the AP2 tranny compensates that almost totally especially in 6th gear. It only plays a role in the (untouched ratio) gears 1-4, which in result are shorter.
OK, there is a tiny bit of difference > total final gearbox drive in 6th gear:
AP1 0,940
AP2 0,922

If I plan on going S/C down the road, would 4.44 gears be fine for DD and weekend tracking once a month or every two months? Also where can I get the "Mazda" 4.44 gears?

Here's a link that may help on the different gears you can get at a Kia or Mazda dealership.
