The sidewinder will fit both bars (round and square). This will not fit onto the factory rack of the Element. Please keep in mind, the Element's factory rack only has a 75 lb weight limit. If you were to remove the factory rack and install a Yakima or Thule rack, you would bump the weight limit up to 125 lbs.

For Yakima, you would need Control Towers, 58" load bars, and 2 sets of Landing Pad 9. This is around $225.
