Hey everybody, I just got my Tein Flex Coilover suspension system installed, I love it. The EDFC was the best investment i made on the car, you can go from race ready to smoother than stock by pushing a button. I wasn't able to install it myself but my mechanic was telling me the EDFC was a little tricky to install, because the little motors need to be put on in a certain way. The edfc is necessary because the way the suspension is attached in the back, you would have to uninstall it change the setting then reinstall it. It took one full day to install then another day for the elighnment. I also got stillen camber and toe angle kits to top it off. I feel like i am riding on rails now. We also lowered it a little and kept it at the same front to rear hight ratio, so it has a really aggressive look.
