Hydraulic Shocks
Good ride and handling are a combination of many parts. Sway bars? LCA's that are boxed? Proper torsion bar tension? Upper arms adjustable? proportion of weight front to back? Rim and tire sizes and weight? Shocks can only do so much to improve your ride.
It's a package deal.
I have KYB's by the way and they are a bit stiff just driving around but when you press them under hard driving conditions they respond....well.
