I need some advice from some fellow mustang owners. I have a little bit of cash to spend and really want to lower my GT/CS with the Ford Racing K springs. I was going to buy them from AM ($209.00) but then found them for much cheaper on Blue Oval industries ($169.00).. seems to good to be true. I have had good experience with AM both in service and product but would really like to save some $$. Anyone here every had any experience with BOI? or know somewhere else I could buy Ford Racing K springs??
