Coil-ex? Eibach?

I have yellow apexi springs right now in my friends car but it feels very hard to me on the road very bad malatyada & nbsp; Maybe if I wear a better quality spring, I say it will be improved. Eibach knew it was good. Everyone recommends it, but also the Coil-ex brand caught my eye. If I bought it, will it be a little improvement, comfort or whatever it is to pay for Eibach?

If you buy eibach, you will be comfortable

But I can buy Eibach's second hand zero Coil-ex and I can not get Eibach zero. I just want it to be a little soft

I use eibach 10 number springs pro kit

I have 3,5 eıbach pro scarce, I am very happy, second hand.
