Selling set of H&R sport springs i bought off a member on here not long ago i never got installed decided not to and go with coilovers. the previous owner put 6-8000k miles on them
From my understanding, the Gen2's weight difference is to much for H&Rs because H&R brand springs drop lower than most others. I have H&Rs on my Gen1 and they sit nearly 2" low. You can use any springs between any Gen and any Mazdaspeed, including 6, the drop and ride is going to vary though.
