I had KYB shocks on a few cars when I was short on cash.
I even had them on THIS car....
Where did you get the chin spoiler?

I had 1.0" torsion bars and Hemi/440 4 speed leaf springs so it was sprung a bit stiffer than stock. It rode sort of rough and wasn't too smooth on rough roads. I read for years that KYBs were too harsh for stiffer springs so I started looking around at other options. Bilstein was a reputable name so I bought a set from Firm Feel. I installed them along with even bigger torsion bars.....1.15" from Bergman Auto Craft. As unusual as it may seem, the car rides smoother and handles better than it did before.
The Bilsteins soak up small bumps but get progressively firmer the further the shock moves. The KYB "Gas-A-Just" shocks are the opposite. They are really stiff from a rest and get softer as they go through their range of travel. I don't understand the reasoning for this design....it defies common sense to me.
