You show you have Z06 chrome wheels on your 2006 XLR I would be interested in doing this to my XLR what year Z06 and can you send me a picture through email at speedway @comcast.net so I can get a better look. ThanksJust found this on ebay:
Obviously the front and rear bumper fascia's are different on the '09 to older models; and the '09 models have the raised hood; but I believe the alignment of hood, fenders, headlights are probably the same, as this was only an upgrade cosmetically to the exterior. So you may be able to make it fit. There may be different mounting techniques, not sure as I am not a mechanic or bodyman, but that seems to be the onle differences I can see---except of course for the ugly side vents.
Just my opinion. You are probably best off to look over an '09 and take some measurements and make sure. Good Luck!!!
