Donald,
My buddy just put on the Wagner TQ Semi-Met's on his F-350 PSD. He didn't want the Ceramics. Ceramics would be the choice I guess, if you have really nice Aluminum Wheels. His are SS.
Also, he got them at AAP online using the Discount Code # DEALIO and got $40 off $100 or more. This is the real deal. This made the price even better than RA when using their 5% off code #.
Plus, there is no shipping changes at AAP on orders over $75. My buddy had ordered pads for the F & R($105.00) But, if they're already in stock @ AAP, then there is still no shipping change.
Look into it!
