Opinions please....
I've always been hesitant on purchasing any "cookie cutter" coilovers that have such a wide model range of vehicles they are available for. Especially since i have been racing spec miata's in the SCCA for the last 8 years and being around so many legitimate race cars. At the track you almost never see shocks that have both threaded bodies for the spring and the body height. JRi, JRZ, Moton, AST, KW,etc all have just the threaded spring adjustment. I'm having AST's built for the ST165 but they are pretty expensive and i would have loved to have spent less but i don't need to lose a wheel or have a shock explode while on track at speed.... the consequent damage and or hitting a wall are way more costly than proper suspension....
