Whats the advantage of this modification

Whats the advantage of modifying the upper arm like this? With rod end on the out side. Adjustability? more length from the upper arm.? Is it needed for the panhard bar? Just found this in a ad on CL was curious.

I'm guessing an attempt to reduce binding by making the upper link straighter ( the stock one is on a pretty savage angle), and a bit of adjustability with pinion angles, as well as correcting geometry on a lowered ride height with the extra mounting points.. who knows if any of it works though.. it looks pretty rough. I wonder what the lower trailing arm mount looks like on the diff? I doubt it is to clear the spring perches.. I have no problems with clearance on mine.

I'll second the adjustability of the pinion angle for either a lowered car and/or for better rear end control at power on at corner exit at wot.
Anyone else notice the left jam nut is loose? Also those welds look like boogers and why not paint them? Weird
Wait a second, that pan hard is backwards from all others I've ever seen... wonder how they managed to get everything to fit around the muffler... no muffler would solve that, which leads me back to thinking this is a track car.
Later edit: the engineer in me had to point out the new setup is in single shear...

Oh yeah - My assumption is that the link was moved out so that standard 5" diameter racing springs can be used. They foul on the stock upper links.

The pics are from a ITA track car that saw for sale on CL. According to the ad it was a pretty successful car. It looks like the reason for the modification is to get around the springs.

That is similar to what MRTE did with the Group B RX-7s. From what I have seen, they just used lower links in the upper position, and mounted them so they would be parallel in side view.
They also had full floating axles. Not sure if Mazda based or if they just used Ford Atlas axles like Toyota did. I DO have the B255 homologation paperwork, I should look into that a bit more.

Thanks for the pic.
So, yes, they trussed the rearend, made it full-floating, and turned the rear links into a Group 4 Escort, which is pretty much what everyone with solid axles were doing.
