They are pretty in-expensive at 166.00 for 17X7. at 17lbs they appear to be a pretty good deal.Enkei makes a racing rim that is 15lbs but i didnt like the design. They were 280.00 a rim.I looked into the 5Zigen FN1-RC or whatever they are called and the spec sheet was that they were 28lbs They are similer to the Motegi rims your mentioned.
