Troy - how similar are the Focus S2 and Focus SVT suspensions?
They are both on a Focus

Honestly I don't know too much detail about the S2 suspension. I can say they are two totally seprate groups. So the outcome will be two completly different handling cars.
You really can't use the base ZX3 as a strong indicator of how well the SVT will handle. Though the chassis dynamics of a ZX3 are good, they are two vehicles designed with two different purposes.
FWIW The ZX3, ZX5, and the Sedan all have the exact same interior dimensions. I think some may be predisposed to the thought that because it's Ford's small car it must be smaller. It's not.
