Ok I see what you mean now. Another good thing to do is to try to get the air out from under the car cleanly.....if you could use a difuser that would be awsome.....but we cant...to bad. But what I do is flare out the back half of the body that seems to help too so it looks like this \_/ the top of that being the back of the body. Yeah I dont remember if the Parma had a lip/splitter on the front but the Proto speed 8 had one.
