Getting started with Aerodynamics

[novaderrik]

The "spoiler" on the bottom of the core support id actually what cools the radiator, not the grill in the front end.

the Monte SS had an airbox that directed the air from the grill to the radiator and closed it off from air getting to it from anywhere else, just like the race car they were modeled after. the chin spoiler under the core support on the SS cars only serves to keep air from getting under the car.

to the OP- do a google image search for 80's NASCAR Monte Carlos. you can see a lot of little things they did to the production sheetmetal to make the cars happy at 200mph.
