Really? Then why make the change? And why make a caster camber plate that is made for a 2011 plus?
because the previous gen GT's mount was a weak design. For the record, the GT500 mount never changed. It's been the same since 2007.
But when you have production going back to 2005, it's not cost effective to change the strut/shock design when it's best to just upgrade the mount to a sturdier design (gt500, steeda hd's etc)
