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)

Springs only, is mainly a comestic thing. Yes they do have some benefits.

But if you want pure performance, coilovers is where its at.

Which claims are you interested in? The biggest claim they make is lowering ride height and that's easy to measure. Since none of these companies advertise their spring rates (or if the springs are linear or progressive rate) that can't be verified. There's not a lot else to scientifically test.

Yeah, the suspension market is full of bs and poor third party references. Lots of my buddy has this and I know a guy etc. No one has track data data and full details of the testing to follow up. Stupid stuff like new suspension but track tires, or new suspension but no rear sway bar, oh forgot to mention that.

Not a ton of technical reliable data that is well supported.

Orb has done tons of research and has found many interesting facts, maybe he will chime in.
