Just a warning...some people find the standard spring rate for the HE's (8kgf/mm front, 6kgf/mm rear) to be a bit too stiff for daily driving. Then again, some people love 'em. I guess it depends on taste and the quality of the roads you regularly drive on. Just don't have any illusions about running a spring 4x stiffer than stock and retaining that Cadillac-like ride quality.
If you buy from a licensed Tein dealer, you can ask about changing the spring rate. I believe you have a range of +/- 2kgf/mm front and rear when changing springs. I think it's something like $50 per spring, but you may be able to custom order up front (I've read that JIC does this).
I was going to buy the HE's, but decided I didn't *really* need the adjustability for my purposes. Not being a track guy, I couldn't really justify the purcahse. I'm getting ready to order a more modest KYB AGX + RS-R Race spring setup.
From all the research I did, they certainly seem to be the most bang for the buck as far as the Tein lineup goes.
Not sure if they're a licensed dealer, but phase2motortrend.com has a good price and they've got a good rep.
