Basicly designed similar Except that I can do a miata top in about 2 hours and an s2k takes much longer (at least for me). I personally prefer Sebring’s and 94-04 mustangs; I could EASILY do two of those in the time it takes me to do an s2k. Damn japs make everything so hard to get to, maybe someone smaller can do it much quicker but im 6'3" 200lbs and I cant fit in the back of the s2k to get to the bolts in the rear, plus all that plastic crap is a bitch to get off, out, and back in without breaking. Is glass really able to be fit into the 00-01? I didn’t know Robbins was making them now, I would have much rather had one of their tops. When I bought mine only electron and GAHH made aftermarket replacements. I don’t particularly like the fit of the electron top and GAHH makes great BMW tops, so I bought my top from GAHH. I did order another plastic window because I was told by them that if I got a glass I would have to unzip it every time I wanted to put the top down. Has anyone tried it yet?
