I bought the Flyin MIata V-Maxx Coilovers from craigslist. I installed them and they seemed fine until an eagle eye viewer noticed that someone had incorrectly assembled them creating a safety hazard. To avoid any danger on track I had to remove, disassemble, reassemble, and reinstall them. I hope that you never have to go through this. This is on my 1990 supercharged 1.6 Miata so it may differ slightly for other Miatas.
