I have in my 2014 4/4 definitely too soft leaf springs. Adjustable Avo dampers help very well since three years, so that the springs do not puncture.

I've had these leaf springs in the following link on my shelf for two years. But I'm not sure if the installation is worth the money.

Has anyone had any experience with it? good or bad...Someone told me they could be too soft.

In my case the Avo dampers have helped that the springs do not touch, but they cannot help that the cardan touches the car when I accelerate with HP plus tuned engine with full tank and with two occupants.

Who has the leaf springs I have on the shelf (see the link) and can tell his experiences? Or should I trade them for these 4 seater 4 blade springs before I invest money in the installation?
