I installed my H&R Drop springs this weekend. That was fun. Couple of take aways. I have a 13 so the front is easier then the 10-12. I had Pepboys swap the front springs. They charged me $52 for the spring swap, and then $89.99 for the alignment. I bought the springs from stage 3 for $262 including shipping. So for $403 and my labor, the springs are in the car. On the front, the two large nut and bolts that hold the strut to the brake assembly are splined. Crack the nut, and bring it flush with the end of the bolt. Then smack the crap out of it with a hammer. I didn't realize this and my trusty breaker bar became an casualty. The rears are really easy. I removed the wheels and tires, and just dropped the sway bar links, and the removed the large bolt that connects the "A" arm into the rear cradle. Use a jack to lower the "A" arm and remove the spring. Really easy. Reverse the steps to install H&R springs. I actually got the rear camber bolts pretty square on with the alignment. Even the tech was like, you did that? All in all it was a pretty easy install, but it was brutal on my knees. I am terrible at documenting things with pictures, but her are the some pictures. When the car settles I will snap some more. I have a stock picture, a leveled rear pic (I cut my PP Springs), and I will have my H&R springs picture soon. I have already noticed better handling and a different ride. I can't wait until she settles.
