I just paid to have the Eibach Pro Kit and J&M APB put on my 2012 GT
. They can't get it aligned quite where I want it with the Eibach Camber bolts so I ordered the MM Caster Camber Plates. They are sitting in my garage. I may put them on this weekend. After watching the mustang shop put the system on I feel confident to do this myself. Then pay to have the car aligned again.... My fault for going cheap the first time. Everything I have read led me to believe these were the best ones to get. I found them for $280 shipped from cjponyparts. Good luck.
