NISSAN SENTRA OLD TSURU Shock Absorbing Car Buffer | eBay

that should just stiffen the suspension up if i am correct? and not absorb SHIT!

Interesting, I was sure it was going to be these:
COILS SPRING ISOLATORS

But the ebay ones attach to the middle of the drooped spring. So it would transmit the "shocks" through the urethane. Could work, but my tech knowledge is limited. I like that it raises the car up a bit, which would counteract the "hyperco stance" that plagues so many of us if these were used on the front. However, those are quite expensive!

When I worked at bmw, new cars that were delivered had something like this installed, car was raised to make unloading easier. Before removing them in the process of the delivery inspection, on the test drive it did seem the suspension was stiffer but I never pushed them hard to see if they had any handling advantages

I've never seen a car with these things on...never. And you're right they are quite expensive. But Maybe they do work...a cheaper alternative than replacing old sagging springs (on certain cars)?????.

Looks like the spacer basically removes one coil from the spring by making it impossible for that coil to compress. This results in a stiffer spring action. The increased stiffness will be more or less proportional to the change in the number of active coils when the suspension is weighted (meaning that if there are 5 active coils and you remove one by blocking it with the spacer, the spring rate would increase 20%, e.g. from 120 pounds per inch to 144). Progressive rate springs work in a similar way. Upon compression, some of the coils that are very close together stack solid, removing them from the spring and increasing the rate as the suspension loads.

Since the spacer more or less maintains the full droop coil spacing after the car is taken off the jack, it also increases the ride height -- it says by 3-5 cm (that's 1.2" - 2.0", which is a lot and could cause unexpected consequences in vehicle dynamics).
