Best Aftermarket Suspension Set-up

I appreciate everyone's input here. It's why I when I'm looking for honest opinions you guys are the best. Over the years, I've talked to Denny regarding his set-up on more than one occasion. QA1 is in my backyard and have always answered my questions and I currently have RMS UCAs on the Dart. All quality setups and that's what why came to you guys. HDK it is for me. Time to make the call.
