Finally had time to install the mirrored wheel covers today. Turned out awesome! When I pull them off next I'm going to strip the clear coat off, do a good buffing to get out some imperfections I noticed, and redo the clear coat.
Steps to do this in case anybody's interested (it was way easier then I feared it would be)
#1 - pull the wheel skirts and rims off, take the rims to your local tire place and have them unseat the bead on the front of the rims
#2 - score a mark where the three screw holes will be on each rim, and mark the location of one of the holes on both the rim and the back of the wheel cover, and number both the rim and the wheel cover (I used a sharpie)
#3 - drill the three holes, and blow out any shavings from in between the rim and tire with compressed air
#4 - tap each hole (I used a #8 32 for these) and once again blow out any debris
#5 - take the rims back to the tire shop and have them re-seated and filled with air (they wouldn't go higher than 45 psi on mine, I had to up it a notch myself at home)
#6 - install the rims back on car, and tighten the lug nuts. At this point I also made sure I had the proper psi in all the tires, since it takes a bit to pull the wheel covers back off to add air
#7 - install the wheel covers - I used nylon washers behind the wheel covers and added a dab of red form-a-gasket in the holes so the screws won't back out
#8- re-install the wheel skirts and enjoy the new look!
