I have a set of rear springs that are on my car and making it sit 4" taller. I have KYB shocks so they have the perches on them (I dont realy want to hear any crap about how you all can afford better shocks). The springs are also stiff as hell.
Soooo, I am looking for some replacements of the right strength, length, and ID. What are these dimentions? For strength I am thinking 165# due to the 255 tires and the 2.7l /6. Where are these sold? I looked at Coleman racing, but all I saw were 3" ID springs and I do not know what length I need. Thanks you for furthering my 914 education in this area (IMG:style_emoticons/default/wink.gif) |

I'm having a similar issue with my Koni reds on my 914-6. I had a set of progressive 165 lbs Welmeister springs on there, and the rear was sitting about 1.5 inches higher than I wanted even with the spring perch at its lowest setting. I swapped out the springs for a set of non-progressive 140 lbs springs with a shorter overall length, and it did drop the rear about a 1/2 inch (and gave me a nicer street ride). But, I will eventually go the Coleman racing route so I can get 'full' adjustability on my ride height and corner weights. You might want to try a set of 140's to soften up the rear end.
Has anyone ever cut a coil or two out of a set of non-progressive springs ala the old hot rodder trick? Not sure why that wouldn't work, but it sure won't help your ride stiffness... Dion |

If you shorten a rod the resulting rod will resist bending more than the original longer rod, in other words be stiffer. If you cut off a coil from a spring you are doing the same thing, shortening the rod, and the resulting spring will be stiffer. There is a formula out there that will tell you how to calculate the results. (IMG:style_emoticons/default/idea.gif) |
