Aerodynamics vs Weigt

At what point does having better aerodynamics out weigh placing more weight in the rear of tahe car? I came up with a design where I am getting sub three times on a street stock car. It is not a wedge but a custom design where I can add just under four ounces in the back. The design does not allow for front fenders but rear fenders can be incorporated into the design in Gen 2. The front wheels both inside and out are exposed to air spillage on either side. So, is getting the most weight rearward more important than the drag penalty associated without running front fenders. I realize that the majority of any cars speed will be in wheel prep so if we establish this as a constant, what do ya think?
 
It seems that aerodynamics always played a very small roll in overall speed and it just seems that lately, it has received much more attention - what changed? Also, what makes the wedge so good compared to very narrow, lightweight bodies?
 
It changed because gone are the days that a few racers were blowing everybody away with better prep products or processes. Back then the few that knew the secrets could blow everybody away with a full sized block. Since DD4H let out his oil secrets a few years ago everybody has perfected that process and now are running very close to each other... Soooo... now aerodynamics and fenders and a bunch of other little things are sorting out the winners from the best.
 
Falcon 777: we're all waiting for the next thing that will makes us faster. If you've got something better than aerodaynamics we'd all be happy to see it at a race. All the cars are engineered with a compromise somewhere.
 
I have incorporated innovative building techniques commonplace in model airplane design and construction and testing them in a few platform that I have designed. My first design is sub 3 secs and I will expand on the second generation based on the excellent information found on this site - really helpful information. There is so much technical theory out there but the bottom line is what the timer read at the end of the track and from that perspective, you guys are dialed in. Once I design, prep, and test the.new design and feel that it can compete with the pros, I will send it in to race. I am also going to build a wedge with fenders and oil prep and see how it compares. This is a great forum - thanks for the info!
