Reducing rear weight / improving weight distribution

[Series8217]

You could put a plastic panel in there easily if you needed to for aerodynamics.

I bet with the engine bay the way it is (no belly pan), the air is already pretty turbulent right there.

My silver car actually had almost a full underbody tray using 3/32" thick ABS. It went from the front of the car all the way to the back of the fuel tank. Only weighed a few pounds if I remember correctly.

I am curious as to how this affects airflow under the car, and how it exits out the rear. I wonder how much the air would catch the bumper and find its way into the rear bumper creating a parachute affect or sorts.

I'm not sure, but I did create large vents in the bottom of the rear fascia to help reduce that affect in case it did exist.

My Corbeau A4s weigh 34 lbs with the stock Fiero sliders attached to them.

if thats the case then thats pretty darn close, if not more than a stock 88 seat with sliders. I think I weighed my 85 gt seats with the speakers in them around 32 lbs with sliders.
