Just so you are clear, The item sold by 949 racing is the oem allignment cam. Their website even lists the part number. Available through Mazdaspeed for $6.78 each or $54.24 for a set of 8.
Like meathead says, 6-8 tightenings is all you get. Put a washer under the nut and you will get another couple tightenings. Then replace.
