[Robert Humphris]

Simple answer to this..

Lower the car to 1/8 inch off the ground, you will now have ground
effect, and air will not flow under the car, to smooth any air that does
lurk in that small space, get polypropalyne sheet, and cut a template of
the under body of the car, rivet the sheet to the underbody of the car,
it is best to use polyprop, as it flexes well, so you cover the
underside of the suspension as well.

On the top remove any guttering , but cutting and welding no more than 4
inches at a time.

Then reshape the front of the car to make it more aerodynamic by driving
at speed into the sloping side of a skip.

What has this got to do with injection

Well of course duct tape will work... All the top 'works' teams use it.
