For those who care about such things. I weighed them 3 different places. When I weighed them at UPS I was surprised when it said 24.3 lbs since I got 20 lbs on my home scale. Then I took them to the Post Office and got the same thing. Hmm, that seems heavy so I took them out of the box and weighed the box. The box weighs 4.2 lbs, a lot more than I would expect. So 20 lbs it is. I do not know what the stock wheels on the EX coupe weigh but I am guessing a few lbs less, maybe 18-19.
The offset listed on the back is 45 ( I assume this is 45mm). I picked them up yesterday from the dealership. They won't go on though until Spring because I want to keep the stock 16's as winter wheels and use the 17's with a nice summer tire. I think they will look sharp on our Atomic Blue Coupe, like the College Hills pics with no underbody kits.
Edit: Should have stated that at home I weighed them out of the box. Stepped on the scale got my weight, then stepped back on holding the wheel (wifes idea).
