exactly. The dampener extends itself when the weight is lifted from it but a stiff spring doesn't need much distance to be uncompressed. What's the spring rate? Just as an example, if the front springs have a 500lbs per inch spring rate on a 2,500lb car with a 50/50 weight balance then both of them are supporting 625lbs. 625 divided by the spring rate (500) means it was only compressed 1.25"...Originally Posted by SoSillyyyy
so.... your saying you adjusted your coilovers and jacked up your car and now you can wabble the spring around? . . . seems normal unless im missing something
Are your wheels off the ground when you jack a car up 1.25" inches or even 2 inches? The suspension has alot more travel than the spring can extend, even if you adjust the pre-load and rebound it won't keep it completely secure, especially on a mid to low grade budget coil-over dampener. This is the reason Eibach makes "helper springs", to keep the spring secure against the top when the car is lifted.
See the small spring on top? That allows the shock/dampener to safely extend
Here is another example of that same helper spring being used under the main spring, it all depends on the application...
Even JIC & Tein use helper springs:
You will just about always have this issue with higher spring rates, it simply cannot extend as long as the dampener and the lower you put the spring perch the more travel and space that will be above it. Hope this helps!
