riko man, everything u have said, from a scientific point of view, makes total sense, combined effects of grip of tire and torque from acceleration will put pressure on the inner section of the wheel, which if it is not strong enough, will simply snap. cant fault u there at all, my chosen science area of expertise admittedly is not physics but geography, but to a scientific mind wot u have said makes total sense! i wanted auto x's for a LONG time, i think they're awesome lookin, but they're over £400 i have sourced a set of Volks for....£170 thats right £170!!!!!!!!!!!!!!!!!!!! u cant beat that with a big stick!!!!!!! even a refurb of £170 and shipping to my gaff will still be under £400! i love it! Keep this debate SCIENTIFIC and NOT opinionated please guys and it can remain open! no slaggin other people off or puttin rota owners down, or it will be closed, if u have a valid point to make please feel free to make it with the necessary backup and this can remain open. Phil.
