I just spent 9 hours straight doing my coilovers on my 325i...Damn I feel like shit! I got some Ground Control coilovers, but when they came in they were for an m3 with stock koni shocks. I had to bore out the hole on the aluminum upper mount that came with the coilovers to go over my shocks. Come to find out I have AC Schnitzer shocks and did not know it! Something else that I don't understand is on the same shock it has a Bilstein logo also? I don't think they are stickers that someone put on there, they look like they are embossed in there...Anyway the car sits how I wanted it, however it is in need of some new shocks badly, I know I should have gotten some too, but I can only do one thing at a time..Thought I would share all that with you all!
