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

On the illustrated crossmember; I do not like that the left and right side LCA pivot points do not appear connected. They hang down and can flex sideways in corners. If that is the case it will be like the 30's/40's Ford beam front suspension with transverse spring.
That is I agree an obvious area that would benefit from a tie bar, just need to resolve the oil pan issue or upgrade to dry sump?
