I wasn't expecting to see people citing the KYB is being too stiff. I put a set on my dad's 63 corvair last fall because the shocks on it were so worn out. After installing the new KYB gas adjust shocks, there is no difference between the KYBs and the old worn out shocks. If I bounced on the bumper, it would continue oscillating up and down about five times, almost as if there was no shock absorber on it at all. So in my experience they were not too stiff, they were way too soft.
