have owned a set of the KW V3 coilovers on an mr2 turbo SW20 for the past couple of year riding it pretty slammed to the floor, have recently started to use it more often and decided to raise it up but it seems that the springs have lost their properties as for example for the car to be evenly raised on one axle, on the left it is at max height and on the right it is half way.

There is something wrong as previously i used to keep them even and the car would remain level.

Hence im thinking that the springs and helper springs have gone.

Could this be?

If so could i get replacement springs possibly not KW, if so what must i measure?
