2. If you look at a JGTC car, they have the lower portion of the bumper removed. This will reduce drag. Someone above stated that there is a pressure difference between trapped air and the wake region. This is infact true! Stagnant air has very high pressure compared to the wake region. The key is to minimize the surface area in which the pressure can act upon, therefore reducing drag. In aerodynamics, every little square inch counts.

I made my own.

I call it a skid plate since I get lots of shit when I tell it creates downforce. I guess you can call it a splitter in a generic sense but my intent is not to restrict air under the front end but to accelerate and drop localized pressure.



the front section converge and then flattens out a quarter and then tapers back up at approx. 4deg to avoid flow seperation with too steep of a gradient. pretty much, it's a generic shape of a typical wing section.


engine cooling becomes an issue so the car is running an oil cooler now.


it sits 4inches off the ground with stock susp.
