Quote: My buddies 68 Drag Radial Chevelle runs 7:60's at 165+ in the quarter & we had a starting line incident one time when the car didn't start. The other guy waited patiently for us to get started. Once the track official gave him the go & we finally got it started we did not have enough time to get the removeable deck lid & wing installed & made a pass anyway without them. We won the race & went 2 MPH faster than it ever has. Made me a believer that all of these big wings on the back make no difference. The car is not at speed long enough to notice.
Rear wings are for downforce, NOT speed. Common sense tells you anything back there catching air will slow you down. I can add 1/2" to the wickerbill on the pro-Mod and slow it down 2 mph, but on a loose track we HAVE to have it up top to keep it stuck.
