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! Don |

kinda hard to explain, i'll try ... on either a car or motorcycle, you have a fairly large mass on top that doesn't move along the axis of the spring (the body of the car) and a pretty small mass on the bottom that does move along the axis of the spring (your wheel). when you drive over a bump, your car stays flat and your wheel moves up/down. it's that imbalance of mass that makes the difference. if your wheel and the rest of the car were about the same mass, it wouldn't matter which way you run the springs ...
