I thought the track was great(I went 3.79) that was our fasted pass to date.and on another note all darts look like darts,cudas,mustang ect. and as far as an advantage I can't see the other car when I'm staged(head pads)and yes it's faster because it's lighter,but hey you built the door car.it's a race car just like yours.over the years I've had my butt wipped by door cars more times than I can remember.the more you worry about me ,the easer you are to beat.just my thoughts( and I already proved that I can crash as good as any door car,I just don't want to do it again)O yea there are easer to work on.(old guys don't like to bent over fenders)
