Not 100% sure what the wheel specs of the Elantra GT Turbo will be but I know the bolt pattern, center bore, and lug size will be exactly the same as the Elantra Sport.

Center Bore: 67.1mm
Bolt Pattern: 5x114.3
Lug Size: M12 x 1.5

The ES has stock wheels of 18x7.5 +55 so I'm sure this would be more than enough info for you to find some great aftermarket wheel ideas.

Me personally, wouldn't mind a set of TE37s (I know, so common and boring) but come on... they look good on anything haha. But I would be interested in swapping tires first on the stock wheels and maybe change rims and tires the year after I've owned it.

What do you have in mind?

I'm not a big fan of wheels with wide designs. I've always like the Intention from Konig, but only in gloss black and a machined face. Their products designs appeal to me and they generally look good on any car.

Which Konig wheel are you thinking about directly. I'm sort of hit or miss with their designs as I am with majority of wheel manufacturers out there. For example: Really don't like this first set, but I do like this second set.
