I always wonder why ppl are so up to modify their cars. Installing spoilers, bodykits, new rims neons etc. Maybe it's about personality, like customizing your own "personal" computer. Maybe its about boosting your performance, like getting better fc or power.

I saw an ad last time for a bodykit for a Camry that has front, back and side skirting and also a stick-on spoiler. Claims that it can improve fc and reduce drag. It got me thinking, we engineers (well, I'm an engineer anyway, so..) spend billions of $$$$ to make the car aerodynamically clean (as in, reduce drag as much as possible) through wind tunnel testing and then some guy comes up with a plastic add-on that can increase stability and fc. Wow, if only things were that easy. Those things only add weight to the car and who knows what the spoiler will do to the car at high speed. Besides, spoilers only work at 100kph ++ and not very useful at low speeds our toll highways can offer.
