yea, i was wondering whether to have them between the rad and the cooler but in the end decided to have them mounted at the front, with the intercooler close up against the rad kinda. still not a easy job by no means and me and my m8 had to cut away a hell of alot the bumper foam and trimmed a slight bit of the lip of the bumper to get the fans to spin freely. there must be mm's in it to be honest
