Arrow Any Professional Comparison/Test Data of Lowering Springs?

So there has been much discussion about Dinan vs. H&R, Eibach, RD Sport...

But besides people's butt accelerometers, do we have any professional reviews on these springs? Do the manufacturers have any proof of their claims? What about track data and comparison? Has anyone test driven these setups back-to-back?

Please support your posts with REAL data and objective/professional opinions. Thanks.

(yes yes yes i know lower=lower center of gravity... but there is much more to automotive suspension than CoG)
