I'm thinking about upgrading the suspension on my 2000 323i. Can someone tell me if there is any difference between the following:

Stress bar
sway bar
Tie bar
strut bar

is this what you are refering tothe strut bar i think is the one that goes across the engine. unless you plan on racing your car its a waste of money i heard its like a placebo effect bmw bodys are tight to begin with. thicker swaybars and modified ie lower your car will give it a stiff ride if you dont mind that.

They could all be the same. The only one that I know about is the sway bar. One thing you get when with the Sport Package on most BMWs is a stronger sway bar...which in turn lowers the car about an inch.

What does it do? It makes the car more responsive in corners. How? Without sway bars and independant susension in a tight or fast corner the car will sink to the outside side of the car as center of gravity mosves to that side because of centripetal force. This is also known as body roll...I beleive. A sway bar runs between the wheels and prevents this by acting as a lever to pull the other side of the car down...the center of the chassis usually being the fulcrum. By pulling the inside down it reduces body roll and makes the car more agile in corners. Of course, this also makes the ride stiffer

Does it make sense? I admit some of my terms may be off, but I am pretty sure about science
