Lowering links are not for everyone. The #1 demographic who don't get along with lowering links are riders labeled as "bolt-on artists" who can't read the instructions and completely bypass the resetting of sag (usually they don't even know how to set sag on a bike in the first place), doesn't properly spring his bike for the extra leverage or raise the fork tubes to decrease understeer or follow basic suspension guidelines. Those riders have bikes that wallow, bottom easily or won't turn.
It's like buying a pair of shoes and not tying the laces, and wondering why you can't run very far before tripping or having a shoe fling off. Easiest to blame the shoe (online in a forum where everyone is an expert), not the shoe wearer.
