YES ROD, just to create enough turbulence to keep the lift off the tail end, That is also why I developed a rear defuser under the Pantera. With a 3.2 R&P I did run up to 200 MPH with complete aero stability. With the stock GTS fiberglass front Spoiler I remember doing my best to straddle the Hwy 318 SilverState centerline badly at 155 MPH MAX, so I developed the race lip GT4 style Air Dam with up to 500 pounds of downforce designed into it and then added a lower wing under it.

An aluminum front hood will actually collapse inward at about the same speed.
