This car does NOT need to pitch rotate to work, it just needs to be set up right. The reason you don't see separation in the photos is because it happens so fast. With the extension set soft, it slams the tires hard at the hit and then sucks the tires back under the car, pretty much stopping any separation or weight transfer dead in it's tracks.

The long bars are fine and will work with leafs, but you have GOT to stiffen up the front segment and stop the axle wind up. I have toyed with the idea of basically eliminating the front segment, replacing it with bars and links, like a short ladder bar and then just using the rear segment to hold the car up.

You would basically clamp the rear leaf like it is now, with no front segment. Put some ears on the bottom of shock plate and run a bar with rod ends to front spring mount. Tabs on top of housing with another bar from there, to right behind front mount. If it sounds like a short ladder bar, that's because it is.
