They are a little lighter, 21.1 lbs for 18x9 or 18.7 lbs for 17x9, but you can get them for whole lot cheaper than the Volk. The Volk looks like 2 or 3 piece design, which mean they will be heavier. The multi-spokes design will also be heavier than 5 or 6 spokes design in general. Check out SSR Competition or Enkei RPF1 if you want something really light in 17".
