I've never really taken a likng to cars, except maybe in body design, so when it comes to anything technical, I'm as lost as a giraffe in Sea World.

Thing is, I'm playing need for Speed: Undergound 2, and to get the best race performance, you have to tune your car for each race mode: Circuit, Drag, Drift, Street X (tight turns) and URL (more compact circuit).

I understand most stuff, but the suspension confuses me.  Especially what's the diffenece between shocks and springs?  Can anyone explain, in layman's terms, what each of the following things does?

• Lowering
• Springs
• Shocks
• Sway Bar

And how changing the setting in the front of back would affect handling?  I'm quite lost.
