DOES THE HDK SUSPENSION K-MEMBER HANDLE BETTER THAN A T-BAR SUSPENSION?

In someways, they are kind of the big dog in the market with enough company funds to do some actual testing. No argument that they probably haven’t, just don’t want to assume.
So that tubular LCA solution they offer is what then, just more light weight something shiny throw it at the wall marketing hype for the gullible? Note, I am using a tad of reverse? sarcasm here.

Same applies to the new rear "upgrades" for Mopar's that basically is 4 link triangulated rear suspension, lifted from an 86 Mustang (and that their owners despise), among others, that is prone to roll binding leading to "snap oversteer" unless enough "slop" is designed into the bushings or "twist" into the control arms, that ultimately offers little.
