who makes best coil over front suspension

I cant wait to get my Hemi Barracuda with the HDK installed. I have had a HDK since 2000. The development of the HDK since 2000 until now is really cool to see. We are friends so I will just say that when I finished my 528 Hemi, 5 speed, 4 wheel disc brake 71 Duster with a flat hood and a HDK front suspension I couldn't believe how nice that car drove and it was in 2 magazines to boot! .......I'm not a PT guy or a rally guy but if you want a great handling, driving Hemi (insert any engine you like here) A-body then the HDK is the way to go.....
