car rides like a tank...the rear is lower than the front
 

i had my suspension replaced with KYB-GR2 all around and now it rides like it's got some load in the back......it's still with the original springs on....
would a lowering springs kit fix the problem and will they work with the KYB's? (i'm thinking Eibach)
thanks a lot !

I think KYB's are little soft for the car. You can't use them with lowering springs either.
 

I think a good setup is Eibach springs and Bilstein sports. Not too low, not too harsh, just right.

My Avant rides low in the back...
 

...with stock springs and Bilstein HD shocks. I think Neuspeed has spacers that move the spring higher on the shock body. It looks like mine could be 3/4" higher but I've become accostomed to the motorboat look!

ECS sells the spacers. Only works with bilsteins.

thank you!
