I`m done spending BIG money on my heap for now and am lookin at ways to make my dart a bit better at speed and wanted to hear/see what you guys have done. My first area was going to be be the rear valance area in which I was thnking about drilling some 1" holes across the back and inside where the support brace is to releave that area of air as it looks like it catches quite a bit. Then I was curious if you guys think air going THROUGH the car would help like; removing the plastic piece that bolts to the inner fenderwell behind the ft. tires and even drillin holes in the doors and door jam to release that pressure area..........almost Indy Car like along w/a ft. air pan. Am I off base here or is it simply back to the "Air needs to go around the car not under it" deal............thankxxx.........
