This one really made a difference in holding down the front end. The Chally used to get very light in the front over 100mph. Added this in front and a TA spoiler in the rear and at 140, it is still very stable.





Wow! Now there's a speedbrake (airbrake for purists) if ever I saw one...

Can't imagine an airfoil attached to a car making much difference for anything important at legal highway speeds. Looks kind of cool though, I guess. I'm sure Walter Mitty would have had one. Could have gotten one on my new Corolla last winter. Figured it was plenty fast enough as it was...
