Keep it all stock man. ZCP is a tremendous handling car. Front strut bar....I don't know what an aftermarket one looks like. I thought there was something already bolted down on top of the front struts. Is there even room for a typical strut bar across the giant plenum?
I think if you need an upgrade that will actually help handling, and not ruin ride quality or driveability. I think solid tube sway bars might do that. It will help plant your inner wheels better to transfer power and grip. Your ride height won't change and your suspension stiffness won't change.
