Can someone explain to me how a shock vs. a spring works in the suspension system? How does changing one vs. the other effect how the E46 handles?
A fine explanation!Technic said:A very simple explanation...
Together, the shock absorber and the spring suspends and isolate the car from the road and determine much of the handling and confort behavior of the car. Individually, they perform specific duties. The spring determines and maintains the height of the car relative to the road while controlling the up and down motion of the suspension to an specific rate (compression/rebounding rate). Left at its own perfect physics, the spring will be rebunding forever if not limited. There are metal (spring and leaf shapes) and air (air or gas filled, electronically controlled containers) springs.
The shock absorber further controls the suspension movement by controlling at what rate the spring will compress and expand. And in increasingly more applications, the shocks can determine when to control that spring rate. In rapid lane changes or sudden braking the shocks can increase its compression piston stroke to limit body lean. Or can decrease its compression stroke for smoother highway ride.
The next time you see a car bouncing all over just driving down a smooth road or severe brake dive, you are seeing a car with worn shocks allowing the springs total control of the suspension.
Agreed 100% although I went there right after reading this post and came up empty. Odd, but I guess their site is a continual work in progress. Just thought I'd mention it to save anyone the trouble...rhenriksen said:
