Query: So far, great performance

I installed these on my 2004 Ford F150 SuperCrew 4x4 with the hope of decreasing my stopping distances,which seemed excessive. They were easy to install, look good and work well with the EBC "Green-Stuff" brake pads. They have been on the truck almost 9 months and are as straight and true as the day I installed them. Absolutely no warping, squealing or anything. Stopping distances have improved so I would recommend this combination over the "parts-store" brand or OEM.
