Mvez very cool info on the built-in helper spring theory. Not shitting on you or what Bilstein says by calling it a "theory"; obviously good enough for 997 gt3/rs, but curious as to why not actual helper spring set up. But very cool to know it's a linear rear in that sense.

Yes; I forgone that thought on the KWCS after purchasing; the twin tube is definitely not track oriented and definitely leaves it far behind when talking about upper echelon suspension groups.

As for spring rate, would you happen to know what the range is? 570/800 to jump to a more track rate like 700/1000 I'd only assume you'd have to revalve and adjust.
