I have all of Autoforms Body parts on my car(hard top, front splitter, wing, S.S. rear diffusers). Simple answer "YES". They make a huge difference. While participating in Viper Days at TMS I loaned out my hard top for a couple sessions, the difference in handleing without the hard top on was much different(WORSE). I had spoken with a few other Illinois members who had their SRT's there and they were complaining about how their cars were not sticking to the track. Well let me tell you, with the Autoform body parts my car stuck like glue all over the track. At VIR earlier this year the 3,000' & 4,000' straight aways felt much safer with the tremendous amount of down force that the splitter and wing created not to mention the upper SS's at 100+MPH
No, they haven't done any wind tunnel testing, they are not Dodge and do not have that kind of money to through around. They have to rely on those of us that have the parts installed to help get the word out. If you know where I can take my car to get the tesing done for free, I will happily do so for definitvie results. Just look at the cross sectional shape of the wing and simple aerodynamics will tell you the wing creates down force. If you want to see a close up picture let me know and I will send it to you or have my buddy Chris post it for me.
Autoform makes excellent parts and "THEY WORK"
