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) |

I agree seperate them so that they aer more easily read and a 2D curve will suffice for each one.
Yes you will not see large changes in either, because that just doesn't happen. The semi trailing arm does not make big changes, but the little changes will make all kinds of problems in a race situation. When your suspension travel is limited to 1-2 inches in both bump and droop, small variations will become big problems. When your chassis is setup to take advantage of 20K lb/degree of twist, and your suspension is setup so that there is no uncontrolled movement, any suspension movement that is not controlled keeps you out of the winners circle. When your chassis is so stiff that your race car setup changes each time you change tires you know you have done it right. |
