I couldn't bring myself to pay a chain mechanic any more to fix my car so I asked a friend how difficult it was to change discs/pads yourself - he said when you change a tyre can, you can do it too. Let's be honest it's not as easy as changing a tire and I asked him to walk me through the process which went perfectly - I've only had the pads/rotors for a day or two so I can't say how good they are will endure. but he said they looked like solid pieces so i think they would be great. My rating so far is 5 stars, everything was labeled and seemed high quality - I've driven a whopping 50 miles since putting them on and they work GREAT. ! I don't often write reviews, but I had to give a special mention to the Power Stop brand. Suffice it to say it's good, each set of shims came with a full color printout with instructions and product details along with a few small packets of lube. The rotors have been marked and fit perfectly.
