To be cool in the car scene:

-Slam car, doesn't matter what you use, BUT IT MUST-BE-SLAMMED.
-Buy at LEAST 8 inch wide wheels, low offset is a MUST.
-Buy tires that don't fit, stretch those things.
-Put a lip on your car, hang something from the back bumper. Anything.
-Colored headlights are a MUST. JDM yellow is good.

Go to meets, stand around, talk about how you scrape this and that and how cool that is.

That's all.
