Some of us have been discussing the 914 rear suspension offline and I measured my toe curve yesterday. I figured I'd share it with the club for discussion.
The axle height scale is in inches and the zero is with the arm level. Attached image(s) |

This is a good site to understand what is happening, although not exactly the numbers we are dealing with, very close.
http://e30m3performance.com/tech_articles/...nter/page-2.htm What we are considering is obtaining a little bit more camber gain, and lessen or eliminating the toe change. In some of our cars, and everyone is running something a little bit different, Roll center MAY be TOO high. In others there is a discussion on how we can change the trailing arm to deal with some of this. There are options, but they need to be researched, not just guessed. This is what Kevin (primariliy) is doing. others are as well. Brett, I was talking about Finches spring stiffness in the actual springs. He is running the car alot stifffer than many of us with regard to spring rate. I would say your numbers for platform stiffness are very close. I don't think I am quite there yet. Hows the Ultimate 914 coming?? Erik |
