or however it goes. Practical testing would require a wind tunnel and a control car, so...I'll suffice for simulations.
Going reading over the majority of your posts you've stated you designed the ground effects and that they increase the car's efficiency to cut through the air. Surely you've done atleast simulations to boast your claims? I'd even accept mythbuster's style circular track lap times/fuel mpg(at the least. I'd still like to see pressure transducers and accelerometers installed, but not everyone has access to those) if you used the stock aero design as a control...but only if you reverted your current setup to test.
