My 914-6 GT Tribute car will for sporting street use with a twin plug carbureted 3.2SS engine. I am not sure if I should be using 100 or 150 lb springs.
Any suggestions? |

During the years of Club Racing, I ran a variety of spring rates. At the end of my racing days I was at linear rate 450 front, 400 rear. Now as just a street toy, I am running progressive rate stacked springs with an effective rate in the droop/compression regime for my car of 150-270 front and 230-330 rear. Spring rate at the shock for the rear is 161-248. The higher effective rate is corrected for the motion ratio of the rear suspension which is about 1.3 for the 914.
If you stick with linear rate springs, they are inexpensive and really easy to change on the rear. I have two crates of linear rate springs that go anywhere from 250 to 700. My car is sprung a little too stiff for the street, but I don't drive it enough to warrant a change plus I do like the way it handles. |
