Just installed the R1 rotors and the ceramic pads that came with this weekend. Wanted to see how well they worked once broken in and seated before spending 200 bucks on the oem pads. Changing rotors only took around 3.5 hrs thats with cleaning out and repacking the wheel bearings. As for the pads they were like glass when first installed. Went through the whole breaking process they recommend which led to some smoking *** rotors burning off that factory coating. Put almost 200 miles on through the weekend and just this morning feels as they are really seating. They seem to grab really really well now. I'm wondering if anyone really bothered to actually break in the pads that came with or just pitched them after trying them out for a day or two. Pretty happy only spending around 250 for the complete package on ebay. Can't beat that deal and they look really nice. Just need to get some rims to show them off now. lol
