I thought I read somewhere our stock wheels were around 22 pounds?
They are (I believe it is 22.5 lbs.).
But to so many on here, you are committing a mortal sin against the god of your choice (or none), and nature, IF you do not at least HALF that factory wheel weight with a replacement.
You are STILL dropping a decent amount of weight, for not a lot of extra coin (or effort/machining costs, etc.), and are NOT looking for every little thousandth of a second on a road course, or autocross course, so GO FOR IT!!
