"Because even though the springs are shorter, they have a stiffer metal. The longer spring sags to the same compressed height vs the shorter, stiffer spring."



Is there any truth to this? I have installed konis on a car which replaced the blown out stock shocks, and it made the ride height increase considerably.
The springs support the weight of the car and the shocks control the motion of the spring...aka dampening aka compression & rebound.


If a shock is supporting the weight of the car then it's most likely going to blow at any time. That's one of the reasons stock shocks on lowering springs will not last long...

1) The stock shock is designed to compress to the minimum length of the stock spring, if you shorten that length (or the spring is too soft) then the car will be supported by and directly impacting the shock on larger bumpers...not good. A blown shock will cause a car to be extremely lofty and continue to bounce several times after every bump...

2) The compression and rebound of the shock is designed to match the spring rate. You lower the spring rate more than 100lbs or so putting too much weight on the shock and it may blow (See note 1). If you raise the spring rate more than 100lbs or so then the shock may not work at all because it can't keep up with the spring. Not saying it will damage the shock but it simply may not work giving the vehicle a rigid/bouncy ride...which leads to bad wheel hop on the drag strip or unpredictable handling in a turn.
