calling .1" difference 'huge rake' is probably an exaggeration. rake is better for handling anyways.
i've been calling them once a month for the past 5 months but there is still no ETA on them to my disappointment. as far as I know H&R has good rep so I'm holding out and waiting to see if it's a good alternative to TRD as a performance spring.
i think it makes sense for h&r to say that there is no industrial standard especially so with progressive springs. tein lists their 3 progressive rates but that doesn't really mean much since different springs probably 'change' spring rates at different amounts of compression so even if you had the numbers it wouldn't be much help to compare with. I guess max rate might be useful but I assume all aftermarket springs to fall in the same ballpark and even then I'm sure there are enough suspension variables that spring rate alone isn't going to give you an answer.

Don't get me wrong, I've got nothing against H&R. My friend has a set on his Bimmer and they are rock solid. H&R is a reputable manufacturer.
I was just saying that, in my opinion, they didn't need to add to the car's already .5" rake. But that's just my taste, and since I am not a racer I wouldn't really see whatever improvements a raked stance might provide.
And 2tc's chart shows Tein as not being progressive...is that not correct?

^yeah my bad, eibachs are progressive, not tein.
asked racing solution for an ETA on the h&r and after they spoke with h&r, they were told not for 2 months at least. so sometime early next year seems to the time. meanwhile, someone close to hotchkis should bug them to get a sway bar prototype since when I called they said they had one planned but not started yet. gotta show interest!

TRD and and Eibach pro kit are the only ones that give even front and rear drops. H&R sports drop 1.4 front and 1.3 rear...and I believe they aren't available yet.
You definitely want the rear dropped more though. Our cars are pretty high in the rear. My sportlines nicely slimmed down the wheel gap in the rear while still maintaining a slightly raked stance.

somebody should create a new thread for this, but there's another spring to add to the list, the tanabe DF210: http://www.tanabe-usa.com/df210.asp?id=1
I called tanabe to find out why it's the DF210 instead of the NF210 listed on their blog. They said that because the springs gave a >1.0" drop, they decided to list it on their DF210 line instead.

from driving perspective yes^
from engineering: there are combinations of spring rates that will set the car in oscillation aka it will forever bounce. When spring rates are calculated, u take the weight distribution into account and wheel base. Front springs gotta come to rest before the rear will hit the same bump blah blah blah but obvi when aftermarket coils/springs are made they take that into account. You just gotta know that if you mix and match or the company sells different combinations of spring rate
