I was trying to track down a set of lowering springs and finally found a set. H&R makes a set and their part number for the 2014 Mazda 6 is 52634. This came directly from H&R. I have contacted a local dealer and they quoted me $252 and would take a month to get to me. I had a sponsor quote me $310 delivered in approximately two weeks. Now I have to convince the wife to let me pull the trigger (rolleyes).
