Doesn't really strike me as that odd. Wagons are so much more popular in AU, that if you want that kind of utility, you'll most likely be getting a wagon anyway. (not that i think it wouldn't be a good option, just sayin)
Oops. Didn't see that the autolite's were the iridium ones.
The gap should be listed on the box. Just make sure they aren't the ones for NA 2.5. (which is .44 I think? )
I have two stockers with new gforce sport tires that you can buy for cheap. Could bring em by on my way back to Fayetteville next weekend. Let me know.
