Yes, welcome to the forum.

I split the Saturn discussion into a new thread. Hope you don't mind.

CarloSW2, you're right that the Mistu VG's were designed to get more airflow onto the downforce-producing spoiler. But even without the spoiler, they had a very small positive effect on reducing Cd (though not likely enough to show up clearly at the pump). The change was less than 0.01, if I recall.
