Help on how to reduce drag
(OP)
Hello we are looking for info on how to reduce the drag on our race car.The car does 160mph in 8.8 seconds on the 1/4mile.
We now feel that we need to look at the aerodynamics for the car to go faster, the frontal area of the car is not very good,we also have to run with 3" ground clearance would a flat floor be the right thing to fit.
you will find photos of the car here

While you've got the Sawzall fired up, turn it into a 7/8ths scale model of what it is now... and of course don't park it near anything similar.

Nice R32 you got there.. At 160mph there is definately some aerodynamic effet coming into play. A completely flat floor (in lightweight fiberglass or other) would definately be a start. In addition, since you're only running the car in drag configuration, you should get rid of the front-mount intercooler (or is that your radiator?) and tape up all of the 'speed holes'. Next step would be to fit wheel covers and finally, a row of shark fins at the top of the rear windshield to promote flow attachment (as fitted to the EVO).
good luck!

There are many books/papers on race cars, including aerdynamics [whole vehicle and details], stability and handling, etc...

I don't know if it'd be sanctioned by your racing body or if the extra downforce would be helpful at all at a drag strip, but the lessened drag could help shave a few tenths of a second off.
