Ok, I have to nit pick here. A shock with a spring around it is not a strut. That is called a coilover shock, or just a coilover. Many cars have coilovers without having struts (most 1990s Honda cars, for example, and many cars have struts that are not coilovers (2nd generation Geo Metro rear suspension, for instance. A strut is a shock that also replaces the upper control arm. It is the defining feature of McFerson type suspension. Basically, they started with a double-wishbone arrangement, except the upper control arm (or wishbone) is removed, and the shock is used to control the angle of the steering knuckle instead. This works because as the end of the lower control arm moves up, it also moves outward, away from the center of the car. That causes the shock/steering knuckle assembly to rotate inward, compensating for body roll. Not all McFerson suspension systems use coilover struts (as in my example above, although most do, particularly in the front of a car. I hope you'll excuse my rant, but this does particularly any me because I have owned a car with non-coilover struts in the back and people will see those and think they're not struts because the design of the car made it more convenient to put the springs next to the struts, rather than around them. Also, my current car is a CR-V which has no struts because its suspension is double-wishbone front and rear, but everybody (including parts stores and manufacturers who should know better) thinks my car has struts because they are all coilovers.

Which is better: reputable strut/shock(gonna use blistein b8 struts) with progressive lowering springs(from reputable company like whiteline) or decent coilovers (1000 to 1500 with no dampening adjustability)Car will be used just for street with comfort with improved handling with less body roll. I really dont play with height setting. Once I find the height I want, I hardly change height setttinh.

Couls you do a quick vid of how the YAMAHA PERFORMANCE DAMPERS work? Is it worth it? Yamaha Performance Dampers are like suspension dampers but for the chassis. they are installed in similar places as the swaybars. Only information i find about htis topic is in Japanesse and Youtube's CC translations are horrible. Would greatly appreciate any type of answer.

You left out that any suspension that is used on the back of the car can be used on the front as well, if the vehicles form factor allows. I cite Jeep Wranglers here.

How you showed the shock absorbers is slightly incorrect. Technically the bottom would move up but in the video the top moves down while the bottom stays still.

Can please someone or somebody tell me or explain the difference between multilink suspension and individual or independent, and which one is better?

If your car has double wishbone, and multilink suspension, your manufacturer cares about handling. Anything less, and you might as well have leaf springs.
