they added the control links i think VX2. all they do is fix a problem experienced with the suspension when the cars a pushed hard, where they get fairly uneven rear tire wear. i think they first brought it in with either the VT2 GTS or VX GTS. but it will be VE when they get a new rear end, but i think its still going to be a mainstream multilink design, ford really broke the mould for IRS with the control blade
