So far so good. Mounts to a full size 2008 Ford F-350 Diesel Club Cab. The brakes have always worked well, but seem to work better (two inches taller) with the bigger Michelin tires. At the same time I did the front brake. I don't care about looks, performance counts as long as everything is good. The time will show. I haven't officially tested it, but braking performance seems to have improved. It also seems to have less dust in it.
