hmmm, i'm sure I remember reading there has been a limited model of the current shape mustang to be fitted with IRS - I shall investigate! If not the Shelby then there must be an even hotter model!

in fact - it looks to be the GT500KR version or something like that - or maybe a tuning company had fitted aftermarket IRS? I saw it on ebay I think....
