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

I am convinced that many of the people in the industry think that Mopar people don't care about handling because they don't buy expensive coil over kits. The GM guys need them and spend the money, and so because the Mopar guys don't they must not care. But maybe instead it is because the Mopar guys are able to do more by updating the stock suspension and it flies under the radar of the industry guys. I think too many of those guys view the world through GM eyes and can't understand because it doesn't fit their paradigm.

Not to say Mopar guys aren't weird, because we are. :)

The GM suspension design definitely has some inherent issues. Like on the Camaro's the motion ratio is terrible. So that's why guys like Dick Gulstrand ran 740 lb/in springs on those cars to set up for racing/handling. You're running a spring rate of 700 something to get a wheel rate in the mid 300's.

Sticks in my head that @72bluNblu put those on his Duster. Maybe I am remembering wrong?

I have them on my Dart GT. The Duster has J-bars in the engine compartment. I haven't tried putting the Duster's 275's on the Dart but my plan for that car was less aggressive, I was only going to run 245's or maybe 255's on it.

My understanding is that the USCT inner fender braces would need to be notched for 275's, although like everything that would depend on the ride height.
