How come you didn't design a J arm for the front suspension? Can get better clearance and strength for rapid suspension movement.

 

Love how it looks now though.

'Splain "J arm" please.  I'm too lazy to look it up.

No not the BMW or the one in the link. You guys are still in street car brain.

 

Off-road racing has its own J-Arm (J Link) design.

 

Here is a quick render I did of what a Datsun off-road J-Arm would be.

Well, all I can say is, "Look back a page or two and see my answer to the 'pillow block' question."

 

I'll save you some time: It never occurred to us.

What's the upside here? Less binding on the ball joint? Or is there less geometry change through the arc?

Pretty much, you can run stock ball joint angles if you pull it off just right. 

 

Based on the fact that our crossmember is spaced down a little over 1" and the struts are 2" longer than stock, our ball joint angles are pretty darn good. They don't come close to binding until you hit full droop, and even then I don't think there's a chance of them binding in real word use. We really aren't that far off of stock 280Z geometry, except that everything is in there backwards...   :P

 

But a better angle would be better...    ^_^

If I had a little more time-money I would donate efforts and a set. 

 

I am out of both and you boys live too dang far away. 

 

Honestly, it wouldn't be hard for us to build them out of steel. It could be done with two stock arms welded together and reinforced.

 

Heck, you could pie cut, reweld, and reinforce just one arm. Only problem is without a donor arm it could get a good bit shorter...
