Did you get them directly from M&H?while pushing my car back into the garage i noticed that the inside is already cracking. they are BRAND NEW.. have 8 passes on them, purchased them over the winter. date code i think is 3 month 2013.
dont think they should be crackin.
I heard the ones off other websites aren't real M&H, but they have the rights to produce them. They aren't stored the same as M&H.
