rear a arm idea?

[anasasisxenophontis]

My bad, I knew the top A-arm was shorter. Got it mixed up. I'll keep that in mind though. I will be drawing up my plans on autocad here shortly, so thats one less thing to worry about.

thanks guys for the feedback. ill post more pic later

So what you guys are saying is- If the upper and lower a arms are the same length and the mounting points on the chassis and the inner cv pivot point are all in line verticly, there should be no or very little plunge in the cv joint. Right

pretty much what will happen, but also you will have a neg camber prob when the chassis leans over to one side..trade off! Thats where things start getting difficult....

Actually If I am thinking right you wish for a bit shorter upper "A" arm. This will add some NEG caster as it compresses and help with handling and keep the outer CV at less angle so potentially if done right it will help with a bit more possible travel ON COMPRESSION. But it can add more angle to the outer CV on droop. Thus the compromise mentioned?

Please correct me if I have erred here. Bill

I dumb...I said in my prev post NEG camber...shoulda said POS camber.... this is an issue with body roll during cornering...not so much as the suspension compresses as a unit (after a jump etc), the car leans and the wheel stays in the same relative camber to the body due to equal length arms and therefore is at POS camber to the road/ground. This is bad for a variety of reasons.

It is therefore nice to have a shorter upper arm which will pull the top of the wheel in as it moves through its arc more than the longer lower arm will due to its larger arc.

Bill you can cater for this by limiting the arm in its droop position (straps or whatever process you like) therefore using the lesser angle on the cv on compression and not letting it get into that "other" unwanted world on droop.
