Flyin' Miata frame rails v2.0
Product Review (submitted on October 25, 2019):
I installed these on a '91 NA with badly squashed frame rails. It took about an hour of hammer work to get the frame rails straight enough to begin the installation. The installation itself was pretty easy. I did it by myself over a few hours, which included adding some sound proofing to the floor pan. The main difference I noticed was more precise turn in and side-to-side transitions in winding roads. My car already has a roll bar and FM shock mount brace that helped to stiffen the chassis. These FM rails definitely added to the overall package. One tip - remove the protective plastic from the rails before installing them. I left it on to reduce scratching as I bolted them in. It is a real pain to get off after the rails are installed!
