My Tokicos give a stiffer ride but it is not bone-jarring by any means. Mine are the non-adjustable version. The adjustable Tokicos have five different settings to allow for greater control over your driving style. Mine is not a corner carver or drag car so I went with the non-adjustable ones. I love them. They helped make my ride feel a lot more solid - and the rest of my suspension is still bone stock.
BTW i'm 30 and they don't bother me
