This installation will add a universal roof rack fairing to the
factory roof rack on a Subaru Impreza wagon.
One of the annoying features of the roof rack is the loud whistling from the
front bar during highway driving. This is an attempt at the cheapest way to add
a fairing to the Impreza Outback Sport, while still maintaining a professional
look. I happened to have the $19.99 Barrecrafters adaptors from a
previous project to adapt a bike rack to the roof rack, as well as on a
Barrecrafters ski rack that I've been quite happy with this winter. Performance
Bike then had their fairing on sale at $20.99, a savings of $10. Sounded like a
good candidate for this project!
- 1 Performance XPORT P-263 Roof Rack Fairing kit (from Performance
1 Barrecrafters UM-100 Luggage Rack Adapter Kit (from Barrecrafters)
3 1/4"x20 x 1/2" bolts, socket head (from any hardware or bike
- Philips screwdriver
- 5/32", 3/16" Allen wrenches
|Locate the three U-brackets, 3 long carriage bolts, and matching
washers and wing nuts. They are shown in the left side of this
picture. Discard them.
One of the Unisport adaptors is shown on the right side, with a
1/4"x20 bolt in place. The UM-100 kit comes with four; since only
three will be used, one will be extra.
||Carefully assemble the
supplied rubber strip or
gasket to the bottom of the fairing, and then fasten the two
outside struts to
Since the outside struts will be stretched to their maximum lengths, the middle
strut cannot be fastened to the middle of the fairing; simply use
the short carriage bolt, washer and wing nut set to plug up the middle
mounting hole, and the wing nut itself will be used as a spacer to
prop up the fairing (see below).
Before fitting the slotted bars or struts to the fairing, straighten
them out slightly at the angle bend, as we will need every length of the
strut to clear the side rails of the roof rack.
Attach three of the Unisport adaptors to the front roof rack bar. Line the two outside
adaptors flush with the gap between the load bar and the plastic
Fasten the struts to the adaptors. The middle strut will "hang" in place, so that the
middle wing nut will rest on top of it. This will help maintain a
slight curve to the fairing and keep it from moving under wind loads.
Adjust the struts and adaptors as necessary to obtain a uniform and
symmetrical fit. Tighten down all bolts.
The fairing is 42" at
its longest part at the bottom. The sides extend beyond the
rain gutters slightly. Also, the fairing sits
about 8" back from the top of the windshield. Although it doesn't
look as macho as if it was lined up with the windshield, this
configuration is probably more effective at eliminating the roof bar
