C4 Front suspension geometry?
Hi all,
I am currently mocking up my cobra kit to accept the front end from a C4 donor and need to understand the relationship between the lower and upper control arms. Mainly the degree offset the upper is from the lower. Does anyone have a CAD illustration or a diagram showing this? I cannot use the C4 K-member due to size and that fact it's bent from the collision. The width apart of the control arms is not an issue, just need to know how the upper relates to the lower.

Most Cobra kit chassis specified which and most offered a suspension member that worked.
Whose kit is yours?
A fabrication of your own maybe?
Your information you feel is based on which C4? '87 and earlier or '88 and later? I've seen earlier that don't match those.

Holy 8-year-old thread, Batman!
But your drawing is still very interesting. Do you happen to know if this is from the early or late C4 front suspension? Judging from the large amount of anti-dive, I'm guess the later version. But can you please confirm?
Also, if you happen to have similar dimensional drawings for the rear it would be much appreciated.

In order for more people to have access, I've uploaded my SolidWorks model of a C4 suspension (late model) on 3DContentCentral
http://www.3dcontentcentral.com/part...&catalogid=171
It is to model the pickup points to study rollcenters, anti-dive angle etc.
It is NOT meant for component fitment
Some parts are greatly simplified Links are modeled as rod ends as I have rod ends on my 1995 Corvette
