Yesterday I installed brake drag reduction clips. I did a
write-up on Insight Central, but it's really easy and took less than an hour.
These are the ones I got at Amazon.com -- Raybestos H6001
Only thing you gotta watch out for is to make sure that you get the little ends of the clips in the right notches. You can see one here at the end of the blue arrow, that's where the ends need to be. It's easy to get the side facing you but harder to tell if the one on the inside the wheel well is facing the right way, so use a mirror or a cell phone to verify proper installation.
