The Ser wheel has a hub bore of 66.1 while the Elantra has 67.1. You will need to have the hub bore enlarged. I know there was at least one member on EXD with those wheels.
There was a wreaked Ser at the shop, so I test fit the wheels on the J2. Aside from the hub being the wrong size, The stock tires are way too big (215/45r17) and they rubbed like crazy (for the J2 anyway, the XD might have more room)
One more thing to consider is the weight, the wheels weigh like 24lbs a piece.
[Edit]
I found the pictures of Elantraxd member playboyz28's Elantra
