I have the opportunity to buy a set of HAL QA1 c/c plates for my stang for a good price. I was lookin at the description of them on summit, and have a couple questions. First, it says for race applications...does this mean they only work with coilovers or something? Second, they say "control arm mount", wtf is this? I thought all pre '05 c/c plates mounted ontop of the strut tower. I wanna get these, but not if they won't work with my mostly stock setup (all I have is Eibach Pro's).
