I would be real surprised if the didn't double as scale pads to measure downforce also. I don't know squat about aero, but it sure seems slick! It may be ugly, but it sure is slow. Girls comb their hair in rear view mirrors and the boys try to look so hard....

What do you suppose the actual cost of wind tunnel testing is per hour??? In the late 80's I knew the guys who built the IMSA Daytonas. They had a session in Marietta, Ga at the Lockhead/Martin wind tunnel. Even then it was many hundreds of dollars an hour. They spent weeks doing everything they could think of to cut the time in the tunnel to save a buck. They let it slip(brag) they had $1 million to build 2 cars, and were sweating every dollar. It may be ugly, but it sure is slow. Girls comb their hair in rear view mirrors and the boys try to look so hard....

It relative low speed and has no floor effects, but you get what you pay far. I'm thinking of approaching a couple of other members who have interest in some tunnel time, with similar cars, and sharing some tunnel time to get the most info on different configurations ans shared knowledge. Looks to me the AJ test might have been just for smoke, wonder with the scoop non functional (as best as i can see from the video) what was learned . I thought it looked pretty clean, but the side flow sure broke up, which I suspect is normal, and I currently have zero tunnel time to back up any of the above. Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
