Hello Fellas, I'm from Taiwan and I looking for the right coilover on my G37s so I spend a lot of time reading the article about coilover for G's. And I noticed that it seems BC and Megan which I think they are the same manufacturer are quite popular in USA!! And BC is made in Taiwan but people in Taiwan always loves JDM stuffs. However, If the price I can get are the same for tein flex z and BC Racing BR. What would you recommend me to get? (Stock suspension is too soft for me to catch my friend's GTI or 1 series on the mountain road where is kinda like canyon in USA but more twisting. I'd be appreciated!!
