The MX5 came with two options of shock absorbers. The Sport model (RS) got flashy Bilsteins and all the other models got boring Mazda made shocks (US models low-end shocks were Tokico, but I can’t see anything on my JDM shocks to indicate the same). I wasn’t lucky, my car isn’t technically Sport spec, so no Bilsteins from factory. Can’t have everything eh?
