The rods weighed-in @ 463 for (2) of them, 462 for one and 464 for one. I shaved a gram off of the heavy one and called it a day. Now I have (3) @ 463 and one @ 462. I studied where the factory seemed to shave them and noticed that the heavy one had a little more meat right here, (in yellow), so I dremeled off a gram from all 4 corners of that rod. It was extremely minor:
There are a lot more pics of spring plates/torsion bars/etc. but my battery is dying and I need to get to work so more later.
EDIT:
The light rod is 462, not 461 grams. I have (3) @ 463 and (1) @ 462 now. The Porsche factory allows 3 grams variance/tolerance so we're way ahead of the game.
