I put mine on a couple of weeks ago. The only problem was manhandling the legs in order to get the bolts to line up. The risers apparently change the geometry. I ruined the hex sockets but the bolts are tight. Hope they stay that way or I'll have to drill them out..
Installed mine the other day. Just make sure you put them on the rack first before drilling to line up the holes. If you have a rack all ready on you will have to make the holes a little bigger cause they do change the way they line up. All in All IIIIIIIIIIII like um. Looks good and makes cleaning easy.
I installed my Kury chrome aluminum rack on my 07 yesterday.
If you look at the back edge where it overlaps the spoiler you can see how the Kury rack edge
has a radius that matched the one on the pre-06-07 wing spoilers.
The new spoiler is straight across the back and, as you can see,
does not align with the rack.
I do not know if Kury (or any others) are offering racks that align
with the straight back edge of the new spoiler shape.
I taped the risers to the legs of the rack, marked the mounting locations, and drilled the holes.
The mounting bolts came as two 1-3/4" and two 2".
The longer ones to the rear legs.
I added some fender washers on the inside to distribute the load.
(I did this on my 02 and it never had a problem with flexing or cracking).
The only problem I came across was with those two longer bolts.
They bottomed out in the legs before the rubber washers started to compress.
I put them in a set of hand bolt shears and in ten seconds they were the length needed
to allow the washers to compress and give a tight fit.
I would have liked the shape of the the rack to match the straight edge of the spoiler,
but I am satisfied with the results.
