So I started putting on my RSD's today and it was all going smoothly. I had them set to the 3" drop according to what the pre-set thread on another forum which is recommended by Buddy Club (miraclegarage) said. The pre-load was about 198 mm and the ride height was set to 100 mm. I bolt up the top first, then the bottom, and then I re-install the upper control arm to the frame and I realize the spring set was hitting the upper control arm. Not a little bit, a lot. Not only that but the pre determined specs provided in the "pre-set" thread were COMPLETELY WRONG. In order to achieve a 2" drop without the lower spring set hitting the upper control arm I had to set the pre-load to 175 mm and the ride height to 82 mm. I don't want to sacrifice performance just to gain the ride height that I desire which is about a 3" drop. Another issue experienced by me and a friend who ordered the same coilovers was that the rear assemblies were a hassle when it came to installing the lower bolt that connects them to the lower control arm. Both my friend and I, unfortunately stripped the (TINY) nut that is welded to the coilover. That nut is not big enough to catch the threads of the bolt and strips quite easily. My friend and I both have roughly 5 years of automotive experience each so it was not an accident caused by ignorance. We had to purchase nuts to put on the other end of the bolt just to be safe (M12-1.25 fine thread). Another thing I noticed is that in order to match up the rear overall ride height with the front, I had to almost max out the rear ride height adjustment which means that even if I were able to get the front as low as I want, the rear would not be capable of it (from my understanding, and what I saw). By maxing out the ride height I mean that the threaded sleeves on the rear were probably within 10 mm of touching the bottom of the lower bracket. I've seen plenty of pictures of people who slam their cars on BC RSD's so I don't understand why I have these issues with even trying to get a 3" drop. As of right now the car is sitting at about a 1.75" drop and it handles like it's on rails and it isn't even as rough or bouncy as everything I've read in the past says. If anyone has any suggestions to helping me figure out how to achieve my desired ride height of a 3 inch drop without cranking the hell out of the pre-load I would appreciate it.

 

ive done quite a few installs.. you're going to want to start from the bottom up.. and adjust the ride height while the coilovers are on the car.. theres no reason why the control arm should ever hit the spring

 

he said it was the lower spring set that was hitting and the settings were preset to what buddy club reps said to set them to.
