I've got the stiffer SE suspension, front and rear strut tower braces, and 19mm rear sway bar.
Still running the stock 15" Sport rims with sticky tires.
Not lowered at all.
Rear drums unfortunately, but upgraded front brakes.
And no ABS luckily.
So a stock SVT isn't to much better than where I am at.
Not putting the SVT down, I really like it, just saying that a Zetec can be modded to hang with and even beat one.
