Anyone running an HDK (Hemi Denny) coilover suspension?

Anyone running an HDK (Hemi Denny) coilover front suspension? Looking to buy a whole kit and his company is the closest one to my house. I know a couple Duster guys that use his kit, just wondering if there's any issues with the E-body kit.
I'm also considering a power steering rack. This is a pro-touring street car with a Hemi mounted with a motor plate.
Thanks.
