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

I agree. The majority of guys that I've seen that change to these coil over systems never drive their cars hard enough to reveal any weaknesses.
Oh, it steers great, it handles so much better....
Yeah, a new 14 to 1 ratio steering rack will feel better than a worn out 24 to 1 manual or a sloppy stock power steering box.
Also, the term handling is a very broad term. To me, handling includes steering response, body roll, front to rear slip angles and oversteer/understeer.
To many people, "handling" seems to mean steering response alone because they don't push the car hard enough to know anything else.
