180 lbs Progressive Springs... Heads Up or Down, Sorry, Stupid Question Time Again Options

[dbledsoe]

I'm installing Bilstein shocks (rear) on my 914 Buick V6 conversion. I bought 180 lbs progressive springs from PP (which were actually shipped from GPR). My question is, does it make a difference how the progressively wound coils of the spring are positioned i.e., close spaced coils should be at the top, or should they be at the bottom?

I apologize for what is probably a very basic question, but doing a search turned up nothing (that I could find to address the question) and I don't have any experience with progressively wound springs.

More photos tomorrow on my slowly advancing Buick V6 into P914 project (this is/was my first 914 [I have two of them now] and my first engine conversion... other than putting a Volvo B1800 engine in a Sunbeam Alpine 28 years ago... and yes I still have it but that was a lot simpler... or maybe I was less hesitant).


Thanks for your help!

I run progesssive springs. Not a single spring but a linear rate spring stacked on top of a progressive rate spring. The progressive rate spring is designed to go into coil bind. I run the heavier linear rate sping on top because I want less unsprung weight near the major moving axis. This is not because I believe that there is any difference in overall spring rate with one or the other spring on top - there is not. However due to the slight difference in the unsprung weight there MAY be a difference in road feel. YMMV.
